Suggestions for Obtaining Service
1
To help ensure your selling dealer provides the level of service you expect, here are some
suggestions we would like to make:
CONTACT YOUR DEALER AT ONCE
Do not wait until you are ready to use your motorhome. Service appointments are made
based on each dealer's schedule, so contact your dealer as soon as possible to have repairs
performed.
PREPARE FOR THE APPOINTMENT
If you are having warranty work performed, be sure to have the right papers with you. Take
your warranty folder and have your vehicle information available. All work to be performed
may not be covered by warranty. Discuss additional charges with the dealer’s service
professionals.
PREPARE A LIST
Provide your dealer with a written list of specic repairs needed. It is important that you
provide any vehicle repair history to the dealer’s service professionals. Keep a maintenance log
of your vehicle’s service history. is can oen provide a clue to the current issue.
BE REASONABLE WITH YOUR REQUESTS
If you leave a list with several items, and you need your motorhome returned back by a
specic time, discuss the situation with the dealer’s service professionals and list your items in
order of priority. is may include making a second appointment for work not completed or
parts that the dealer may need to order.
DON’T EXPECT TO LOOK OVER THE TECHNICIAN’S SHOULDER
Please don’t be oended if you are told you cannot watch the work being done. Some
insurance requirements forbid admission of customers to the service area.
INSPECT THE WORK PERFORMED
Finally, check out the service or repair job when you pick up your motorhome. Notify the
dealer’s service professionals immediately of any dissatisfaction. If you cannot return the
vehicle immediately for repair, make an appointment as soon as possible.

Replacement Parts
1
NOTE: Damage caused by use of your
motorhome in freezing temperatures is
not covered by the Thor Motor Coach
Limited Warranty or the Thor Motor Coach
Structural Limited Warranty.
TMC does not sell parts retail direct. Please contact your selling dealer for assistance in
obtaining replacement parts or accessories. If the original part is no longer available, we will
make every eort to provide an appropriate substitute.
Cold Weather Usage
When RVing in freezing or below freezing temperatures, these precautions should be taken:
• Make proper preparations to avoid freeze-ups of the fresh water and drainage systems.
• Propane gas and sucient power is needed for protection from possible freeze-ups of the
propane gas regulator.
• During cool weather usage, ventilation or addition of a dehumidier (customer supplied)
may be required to reduce condensation.
• To avoid damage, check the outside extrusions for frozen moisture before operating or
using the motorhome compartment doors, locks, slideouts, windows, vents, etc.
Extended Stay Usage
Your motorhome was designed primarily for recreational use and short-term occupancy.
If you expect to occupy the motorhome for an extended period, be prepared to deal with
condensation and the humid conditions that may be encountered.
e relatively small volume and tight compact construction of modern RVs mean that the
normal living activities of even a few occupants will lead to rapid moisture saturation of the
air contained in the motorhome and the appearance of visible moisture, especially in cold
weather.
Just as moisture collects on the outside of a glass of cold water during humid weather,
moisture can condense on the inside surfaces of the motorhome during cold weather when
relative humidity of the interior air is high. is condition is increased because the insulated

walls of a recreation vehicle are much thinner than house walls. Estimates indicate that a
family of four can vaporize up to three gallons of water daily through breathing, cooking,
bathing, and washing.
Unless the water vapor is carried outside by ventilation, or condensed by a dehumidier
(customer supplied), it will condense on the inside of the windows and walls as moisture, or
in cold weather as frost or ice. It may also condense out of sight within the walls or the ceiling
where it will manifest itself as warped or stained panels. Appearance of these conditions may
indicate a serious condensation problem.
When using your motorhome, you should at all times take necessary action to minimize the
eects of excessive moisture and condensation. For tips on controlling condensation see the
“Tips To Controlling Condensation” section.

cannot form in dead air spaces. Allow air to circulate inside closets and cabinets (leave
doors partially open). Please keep in mind that a closed cabinet full of stored goods
prevents circulation and allows the exterior temperature to cause condensation.
• A natural tendency would be to close the motrorhome tightly during cold weather. is
will actually compound the problem. Simply put, you need to remove some of the warm
air and allow some cool outside air to get inside the motorhome, so the furnace will not
recycle the humid interior air.
• Use uorescent or LED ceiling lights and minimize prolonged use of incandescent lights,
which produce heat and contribute to condensation in the roof area above the ceiling lights.

Aer you rst purchase your new motorhome and sometimes aer it has been closed up for
an extended period of time you may notice a strong odor and chemical sensitivity. is is not
a defect in your motorhome. Like your home, there are many dierent products used in the
construction of recreational vehicles such as carpet, linoleum, plywood, insulation, upholstery,
etc. Formaldehyde is also the by-product of combustion and numerous household products,
such as some paints, coatings, and cosmetics. However, recreational vehicles are much smaller
than your home and therefore the exchange of air inside a recreational vehicle is signicantly
less than a home. ese products, when new or when exposed to elevated temperatures and/
or humidity, may “o-gas” dierent chemicals, including formaldehyde. is o-gassing,
in combination with the minimal air exchange, may cause you to experience irritation of
the eyes, nose, and throat and sometimes headache, nausea, and a variety of asthma-like
symptoms. Elderly persons and young children, as well as anyone with a history of asthma,
allergies, or lung problems, may be more susceptible to the eects of o-gassing.
Formaldehyde
Most of the attention regarding chemical o-gassing surrounds formaldehyde. Formaldehyde
is a naturally occurring substance. It is also a key industrial chemical used in the manufacture
of the numerous consumer products which we referred to above and used in the construction
of recreational vehicles. Trace levels of formaldehyde are also released from smoking, cooking,
use of soaps and detergents, such as carpet shampoos, cosmetics, and many other household
products. Some people are very sensitive to formaldehyde while others may not have any
reaction to the same levels of formaldehyde. Amounts released decrease over time.
NOTE: Chemical off-gassing is not a
"defect" in your motorhome and is not
covered by the Thor Motor Coach Limited
Product Warranty or the Thor Motor Coach
Structural Limited Warranty. Please follow
the recommendations in this section to
address this concern.

Ventilation
To reduce or lessen exposure to chemicals from o-gassing it is of utmost importance that you
ventilate your motorhome. Ventilation should occur frequently aer purchase and at times
when the temperatures and humidity are elevated. Remember o-gassing is accelerated by
heat and humidity. Open windows, exhaust vents, and doors. Operate ceiling and/or other
fans, roof air conditioners, and furnaces. Use a fan to force stale air out and bring fresh air in.
Decreasing the ow of air by sealing the recreational vehicle increases the formaldehyde level
in the indoor air. Please also follow the recommendations contained in this section regarding
tips to avoid condensation problems. Many of the recommendations contained here will assist
in avoiding exposure to chemicals that o-gas.

Mold
What are molds?
Molds are microscopic organisms that naturally occur in virtually every environment, indoors
and out. Outdoors, mold growth is important in the decomposition of plants. Indoors,
mold growth is unfavorable. Le unchecked, molds break down natural materials, such as
wood products and fabrics. According to the Center for Disease Control, exposure to damp
and moldy environments may cause a variety of health eects, or none at all. Some people
are sensitive to molds. For these people, molds can cause nasal stuness, throat irritation,
coughing or wheezing, eye irritation, or, in some cases, skin irritation. People with mold
allergies may have more severe reactions. Immune-compromised people and those with
chronic lung illnesses, such as obstructive lung disease, may get serious infections in their
lungs when they are exposed to mold.
What factors contribute to mold growth?
For mold growth to occur, temperatures, indoors or outdoors, must be between 40 degrees
and 100 degrees Fahrenheit and also have a source of moisture, such as humidity, standing
water, damp materials, etc. Indoors, the most rapid growth occurs with warm and humid
conditions.
34 CUSTOMER CARE | 877.855.2867
How can mold growth be inhibited?
By controlling relative humidity, the growth of mold and mildew can be inhibited. In warm
climates, use of the air conditioner will reduce the relative humidity. Vents are located in the
bathing and cooking areas and constant use is advised during food preparation and bathing,
even during colder weather. Additionally, opening a window during these activities will assist
in ventilation. In extremely humid conditions, the use of a dehumidier can be helpful.*
Frequent use of your motorhome or cleaning regularly is an important preventive measure.
Further, any spills should be wiped up quickly and dried as soon as possible. Avoid leaving
damp items lying about. On safe surfaces, use mold or mildew killing cleaning products.
Check sealants regularly, and reseal when necessary to avoid water leaks. Proper preventive
maintenance to the motorhome and its accessories, as described both in this manual and in
accompanying literature, will provide the best protection for your motorhome.

Tires and Wheels
Uniform Tire Quality Grade Standards (UTQGS)
is section of your owner’s manual contains tire safety information as required by the
U.S. Department of Transportation (DOT) National Highway Transportation Safety
Administration’s (NHTSA) 49 CFR 575.6 Uniform Tire Quality Grade Standards (UTQGS).
e UTQGS is intended to aid consumers in making informed choices in the purchase of
passenger car tires.
Tire ratings are located on the sidewall of passenger tires sold in the United States (except
deep tread, winter-type snow tires; space-saver or temporary use spares; tires with normal rim
diameters of 12 inches or less; or limited production tires).
e UTQGS rates tires by treadwear, traction performance, and temperature resistance.
Treadwear
e treadwear grade is a comparative rating based on the wear rate of the tire when tested
under controlled conditions on a specied government test course. For example, a tire graded
150 would under one and a half (1-1/2) times as well on the government course as a tire
graded 100. e relative performance of tires depends upon the actual conditions of their
use, however, and may depart signicantly from the norm due to variations in driving habits,
service practices and dierences in road characteristics and climate.

Traction – AA, A, B, and C
WARNING
The traction grade assigned to a tire is based on braking (straight ahead) traction
tests and does not include cornering (turning) traction.
e traction grades from highest to lowest are AA, A, B, and C, and they represent the tire’s ability
to stop on wet pavement as measured under controlled conditions on specied government test
surfaces of asphalt and concrete. A tire marked C may have poor traction performance.
NOTE: Always pay close attention to the
condition of your motorhome's tires

Temperature – A, B, and C
WARNING
The temperature grade is established for a tire that is properly inated and not
overloaded. Excessive speed, under ination, or excessive loading, either separately
or in combination, can cause heat buildup and possible tire failure.
e temperature grades are A (the highest), B, and C, representing the tire’s resistance to the
generation of heat and its ability to dissipate heat when tested under controlled conditions on
a specied indoor laboratory test wheel. Sustained high temperature can cause the material of
the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire
failure. e grade C corresponds to a level of performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety Standard No. 109. Grades A and B represent
higher levels of performance on the laboratory test wheel than the minimum required by law.
Temperature Grades Speed in Miles per Hour
A Over 115 MPH
B Between 100 and 115 MPH
C Between 85 and 100 MPH

DANGER
Failure to follow proper ination guidelines may result in tire failure, which, under
certain circumstances can cause loss of vehicle control or accidents that may result
in property damage, bodily injury, and/or death.
WARNING
It is recommended that the tire pressure be checked at the beginning of each trip
to obtain the maximum life of the tire. Follow the instructions listed on the Federal
Certication label to determine the correct tire pressure.

• Proper care and maintenance of your motorhome tires is essential to ensure your safety, as
well as the safety of others, as you travel.
• Routine maintenance on your motorhome is important, but it cannot be overstated just how
critical proper tire maintenance is to the safety, operation and durability of your new vehicle.
• You must follow the manufacturer’s ination guidelines for maximum load capacity; underination is just as dangerous as over-ination.
• To insure your motorhome tires are operating safely, regular inspection of your tires and
checking tire pressures is absolutely mandatory.
• Examine your motorhome tires frequently for unusual wear. Alignment, balance and
bearing wear will aect tire wear. Make sure to look for cracking, bulging, uneven tread
wear, etc.

When you are using your motorhome, check the ination pressure of each tire weekly to
insure maximum tire life and travel wear. Tire pressure should only be checked when the tires
are cold. During travel, your tires heat up and the air pressure inside the tire increases.
Lug Nut Torque
Being sure wheel mounting nuts (lug nuts) on the wheels are tight and properly torqued
is an important responsibility that you need to be familiar with, and practice. Inadequate
and/or inappropriate wheel nut torque (tightness) is a major reason that lug nuts loosen in
service. Loose lug nuts can rapidly lead to a wheel separation with potentially serious safety
consequences.
Refer to the chassis manufacturer's information for proper lug-nut torque and tightening
sequence.
40 CUSTOMER CARE | 877.855.2867
Tire Inflation
Your tires and wheels support the entire weight of your motorhome and its contents. Your
tires are also the only contact your motorhome has with the road surface. Determining and
maintaining proper ination is the most important factor in maximizing the life of your tires.
Driving on a tire that does not have the correct ination pressure for the vehicle load is
dangerous and may cause premature wear, tire damage, tread delamination and/or loss of
control of your motorhome.
Underinated tires can lead to disaster. Avoiding this is quick and easy:
• FIND YOUR PSI. Your PSI is the pounds per square inch of air pressure that’s right for
your tires. e correct PSI for your tires is located on your motorhome’s tire information
label – not on the sidewall of your tire.
• CHECK IT MONTHLY. At least once a month, check all your motorhome tires air
pressures (including the spare tire) using an accurate pressure gauge. Bottom line: you
cannot tell if your tires are underinated just by looking.

Alignment
NOTICE
The front suspension and steering system of this motorhome was factory aligned
prior to it being dispatched to the dealership. The alignment is however, greatly
affected by the way the unit is loaded prior to travel. This loading includes how
much cargo, water, and LP are carried as well as the distribution of said cargo. Thor
Motor Coach advises to have the alignment checked in the fully loaded condition
(the way you would normally load the unit to travel). Not having the alignment
checked and reset can result in abnormal tire wear.

Changing a Spare Tire (if so equipped)
WARNING
Do not use the leveling jack system to support the motorhome while under the
vehicle or changing tires. The leveling system is designed as a leveling system
only. Do not use the leveling jack system as a jack or in conjunction with a jack.
If a tire change is required, it is highly recommended the work be performed by a
knowledgeable trained professional. Attempts to change a tire while supporting the
motorhome with the leveling jack system could result in damage to the motorhome
and risk causing serious injury or death.
WARNING
When replacing a tire, make sure to replace it with a tire of the same size and
specications listed on your motorhome’s Federal Weight label.
WARNING
The motorhome is very heavy. Raising the motorhome to replace the spare tire
should only be done with extreme caution by a qualied technician. The vehicle
could slip, causing personal injury or death. DO NOT ATTEMPT TO DO THIS
YOURSELF.
If you experience a at tire while driving your motorhome, gradually decrease your vehicle
speed (if possible). Hold the steering wheel rmly and direct the motorhome to a safe place
on the side of the road. Please contact a road service provider, a qualied RV service repair
center, or 911 in the U.S. for assistance. It is highly recommended you do not attempt to
change a spare tire or jack the motorhome yourself; this is why a jack handle has not been
included with your motorhome.

Tire Identification Information
TIRES AND WHEELS
To maintain the load capacity of your motorhome, it is vitally important to only replace
worn or damaged tires with tires with ratings equal to or higher than what was originally
equipped on your vehicle. e illustration, located on the next page, describes important tire
information that is embossed on every tire by the manufacturer.
e Load Index may be indicated with two numbers separated with a forward slash. e rst
number is the load index of the tire congured as a single tire on a single wheel. e second
number indicates the load index of the tire as a dual-wheel conguration. Multiplying the second
number by 2 will give you the total Load Index for the dual wheel conguration.
e load index per tire congured as dual wheel is less than a single tire to provide a margin of
safety for the load-carrying capacity of the tire in the event that one of the dual tires is punctured or
otherwise fails.

Weighing Your Motorhome
When loading your cargo, be sure it is distributed evenly to prevent overloading front to
back and side to side. Heavy items should be placed low and as close to the axle positions
as reasonable. Too many items stored on one side of your motorhome may overload a tire.
Periodically weigh your motorhome at a public scale to determine axle loads.
WEIGHING, LOADING, AND TOWING
To weigh your motorhome correctly, measure the fully loaded vehicle axle by axle and wheel
position by wheel position. You can nd certied public or commercial vehicle scales at
moving and storage lots, farm suppliers with grain elevators, gravel pits, recycling companies,
and large commercial truck stops. You can also look in the telephone book under “weighers”
or “weighing”.
Allow adequate time, since the entire weighing process can take around 30 minutes. ere
may be a small fee for each weight taken, but the expense is a worthwhile investment toward
the safe and economical operation of your motorhome.
Your motorhome must be weighed fully loaded. at is with passengers, food, clothing, fuel,
water, propane, supplies etc. Any towed vehicle (car/pickup, boat, or trailer) or item loaded on
brackets on the back of the motorhome should also be included in the weighing.
e following procedure is suggested when using a long platform scale, although any method
recommended by the scale operator which correctly determines weight value is acceptable.
During all measurements, it is important to keep the vehicle as level as possible.
1. Pull onto the scale so that only the front axle is on the platform with the end of the scale
midway between the front and rear axles and record the weight (Reading A).
2. Pull forward until the full unit is on the scale and record the weight (Reading B).
3. Pull forward so that only the rear axle is on the scale and record the weight (Reading C).
Reading A: Front
4
Reading B: Total Coach
Reading C: Back
NOTE: Thick Black Lines in the illustrations
above represent a vehicle weighing scale.
4. To determine the weight of individual wheel positions, repeat the previous three steps, but
this time, use only one side of the motorhome on the scale. Record the weight readings. To
calculate the wheel position weight for the opposite side of the motorhome, subtract these
weight readings from weight readings A, B, and C recorded in steps 1, 2, and 3.
Your motorhome must remain as level as possible on the scale, even though an axle or side
47THOR MOTOR COACH | MADE TO FIT
WEIGHING, LOADING, AND TOWING
is not physically on the scale. To obtain the side-to-side weights, there must be enough
space on either side of the scale to allow the motorhome to be partially o the scale.
4
NOTE: Additional cargo carrying capacity
can be obtained by reducing the amount of
fresh water carried while driving.
For improved accuracy, or Motor Coach recommends using a segmented 4-pad scale, when
possible, to determine individual wheel weights. e corner weights should not exceed half of
the respective Gross Axle Weight Rating (GAWR) or the maximum load rating for the tire or
set of dual tires at the rear, whichever is less.
Individual wheel position weights must not exceed the maximum tire load capacity. e
maximum load rating for the tire can be found embossed on the tire’s sidewall.
If any of the corner weights exceed half of the listed GAWR or tire ratings, relocate the
passengers and redistribute or remove a portion of the cargo until the weight is within the
proper limits for all four corners of the vehicle.
Check your motorhome vehicle weight periodically to obtain optimum mileage from your
tires, and to improve vehicle handling. Tires should always be inated as recommended in the
chassis manufacturer’s instructions or on the tire sidewall (refer to your Chassis Packet).
Weight Distribution
Improper weight distribution or too much weight on your motorhome’s suspension system
can cause spring, shock absorber, or brake failure, handling or steering problems, irregular
tire wear, tire failure, or other damage. An overloaded motorhome is hard to drive and hard
to stop. In cases of serious overloading, brakes can fail completely, particularly on steep
hills. e load a tire will carry safely is a combination of the size of tire, its load range, and
corresponding ination pressure.
48 CUSTOMER CARE | 877.855.2867
Loading Tips
Store and secure all loose items inside the motorhome before traveling. Overlooked items such
as canned goods, or small appliances on the countertop, cooking pans on the range or freestanding furniture items can become dangerous projectiles during a sudden stop. Distribute
cargo side-to-side so the weight on each tire does not exceed one-half of the GAWR for either
axle. For traveling safety, it is important to make sure any tie down straps (if so equipped) on
appliances or furniture are secured.
Packing for Travel
WEIGHING, LOADING, AND TOWING
Pay careful attention to where and what type of ammable materials you store. Certain storage
areas are clearly labeled DO NOT STORE COMBUSTIBLE MATERIALS. Examples of spark
producing areas, depending on the motorhome model, are: base kitchen cabinets, front
dinette base, exterior refrigerator service compartment, as well as refrigerator cabinet. Please
use discretion as to what potentially dangerous products your motorhome contains while
traveling. Be sure all canisters and bottle tops are secure and leak free.
e following checklist will assist your preparing the living quarters for a trip:
• In winter, make sure that the fresh water system is freeze protected.
• Make sure that all storage items are secured, and heavy items are stored low so they do not

Chassis Alternator
e 12 volts DC chassis alternator supplies power to both the automotive systems as well as
any auxiliary battery if equipped, and directly to the motorhome living quarters while the
vehicle motor is running. e alternator compensates for electrical usage in the vehicle, the
power drawn by lights, fans, and other 12 volt powered items as well as the charging of the
automotive and auxiliary batteries.
53THOR MOTOR COACH | MADE TO FIT

CHASSIS
If the alternator is not keeping pace with the draw on your motorhome’s electrical system while
driving down the road, it means it is working in a negative mode: more power is being used
than the alternator is putting out. is means that you are taking power out of the batteries. If
you draw too much power from your batteries there may not be enough power le to start the
motorhome or run any of the 12 volts DC appliances when you stop for a break or for the night.
e alternator will charge at a higher rate right aer the motorhome has been started,
replacing the power used to start the vehicle, but the charging should quickly go back to
“normal” and hold its own even when you turn on lights or appliances.
If the alternator shows a discharge while the motor is running, turn OFF appliances and lights
to see if a charge comes on or if the alternator indicates “neutral”. en apply a drain on the
system to see if a discharge returns. If a discharge persists, contact your dealer.
When stopped at a campsite that allows you use of the shoreline, the 120 volts AC electrical
system will recharge your auxiliary battery. Under heavy usage in warm weather, check the
uid level of those batteries that require attention to uids quite oen. Low battery uid level
is very harmful to the battery’s longevity.

consumption from discharging the chassis battery while the motorhome is parked.
Some additional characteristics of the battery isolation manager include:
CHASSIS
1. e isolator electrically delays connecting the house batteries to the vehicle charging
system for approximately 15 seconds, to allow the alternator time to reach full charging
ability.
2. Aer this initial time delay, the isolator senses the voltage of the vehicle charging system.
e isolator connects the house battery to the vehicle’s charging system only when the
chassis charging system reaches the correct voltage.
3. If the vehicle’s charging voltage drops below 13.2 volts for a period of 4 seconds, due to
low idle speed and/or excessive load, the isolator will disconnect the house batteries until
the vehicle’s charging voltage returns to a level of 13.2 volts or above. For this feature, there
is a built-in delay period of approximately 10 seconds.
4. e isolator allows the chassis battery to be charged by the house charging device (usually
the converter or inverter) when 120 VAC is in use (shore power or generator power).
5. e isolator allows vehicle starting from the house battery(ies) via the Emergency
(Auxiliary) Start Switch.
Emergency (Auxiliary) Start Switch (if so equipped)
Your motorhome may be equipped with an Emergency (auxiliary or Aux) start switch.
Located in the vehicle’s cockpit, near the drivers seating area, this switch connects the house
battery to the vehicle’s starting circuit. is feature is used for situations when the chassis
battery is too depleted to start the vehicle on its own. Connecting the house battery to the
chassis battery may provide the needed energy to start the vehicle’s engine.
NOTE: Do not hold the ignition key in the
start position for more than 30 seconds. Be
careful not to run down the auxiliary battery
as this could leave you without 12 volts DC
power.

FUEL SYSTEMS
A fuel transfer system allows you to store gasoline for use in motorcycles, snowmobiles, ATVs,
or other vehicles and equipment while at a campsite. is system consists of a fuel tank, fuel
tank ller, fuel gauge, fuel transfer pump, fuel transfer valve and hose with ll nozzle. A master
pump switch is located on the inside control panel and an emergency shuto switch is located on
the frame rail near the fuel transfer pump. A metal ground clip reduces the possibility of static
electricity discharge between the fuel station and the equipment being fueled.
To ll the tank, remove the fuel ller cap and ll the tank with the grade of gasoline required
by your equipment. When replacing the fuel ll cap, be sure it seats squarely and turn it rmly
to lock it on the ll pipe neck.
Fuel Transfer System Safety
Static electricity-related incidents when refueling are extremely unusual. ey appear to
happen most oen during cool or cold and dry climate conditions. In rare circumstances,
these static related incidents have resulted in a brief ash re occurring at the ll point. You
can minimize these and other potential fueling hazards by following safe refueling procedures.
NOTE: The diesel generator requires 12
volts DC power from the house auxiliary
batteries to start, and draws diesel fuel
to operator from the chassis fuel tank.
If the fuel level to the chassis fuel tank
drops to or below ¼ full, the generator
will automatically shut OFF and cannot be
restarted until the fuel tank is filled to above
¼ full.

FUEL SYSTEMS
A build-up of static electricity can be caused by reentering a vehicle during fueling. If you
return to the fuel ll pump during refueling, the static may discharge at the ll point, causing a
ash re or small sustained re with fuel vapors.
Here are some additional refueling safety guidelines when refueling a vehicle or lling up fuel
storage containers:
• Turn OFF vehicle engine. Disable or turn OFF any auxiliary sources of ignition: the
furnace, water heater, stove, oven, and any pilot lights, etc. Turn OFF the main propane
valve.
• Do not smoke, light matches or lighters while operating the refueling system, or when
using fuel anywhere else.
• Use only the refueling latch provided on the fuel dispenser nozzle.
• Never jam or otherwise try to lock the refueling latch on the fuel ll.
• Do not re-enter your motorhome during refueling. If you cannot avoid re-entering your
vehicle, discharge any static build-up BEFORE reaching for the nozzle, by touching
something metal with a bare hand, such as the vehicle body or frame that is located away
from the nozzle.
• In the unlikely event a static-caused re occurs when refueling, leave the nozzle in the ll
pipe and back away from the vehicle. Turn OFF the fuel pump master switch immediately.
• Do not over-ll or top-o your vehicle tank, which can cause fuel spillage.
7
• Never allow children under licensed driving age to operate the pump.
• Avoid prolonged breathing of gasoline vapors. Use fuel only in open areas that get plenty
of fresh air.
• Keep your face away from the nozzle or container opening.
• Never siphon fuel by mouth. Never put fuel in your mouth for any reason. Fuel can be
harmful or fatal if swallowed. If someone swallows fuel, do not induce vomiting. Contact
an emergency medical service provider immediately.
• Keep fuel away from your eyes and skin; it may cause irritation.
• Remove fuel-soaked clothing immediately.
• Use gasoline as a motor fuel only. Never use gasoline to wash your hands or as a cleaning solvent.

Propane System
Propane or liqueed petroleum (LP) gas is a clean and ecient form of energy when proper
handling and safety precautions are observed. e propane system in your motorhome
furnishes the fuel for cooking, heating, hot water and propane generator (if so equipped).
Propane can also be used as an alternative energy source for refrigeration.
e propane system is comprised of numerous components such as the propane container,
hoses, propane gas regulator, and piping and copper tubing lines to each appliance. Propane
is heavier than air; the gas tends to ow to lower areas and will sometimes pocket in these low
areas, such as the oor.

WARNING
THIS PROPANE PIPING SYSTEM IS DESIGNED FOR USE WITH PROPANE ONLY.
• Do not connect natural gas to this system.
• Securely cap inlet when not connected for use.
• After turning on propane, except after normal cylinder replacement, test propane
piping and connections to appliances for leakage with soapy water or bubble
solution.
• Do not use products that contain ammonia or chlorine to test for leaks. These
substances may weaken piping components and cause gas leaks, leading to re
or explosion, which could result in death or serious injury.
WARNING
Gas cooking appliances need fresh air for safe operation. Before operating:
• Open vents or windows slightly or turn on exhaust fan prior to using cooking

• Gas ames consume oxygen, which should be replaced to ensure proper
combustion.
• Improper use can result in death or serious injury.
Propane is a colorless and odorless gas that, in the liqueed state, resembles water. An odorant
(usually a sulfur compound) is added as a warning agent. If you smell propane within your
motorhome, quickly and carefully perform the procedure listed on the label to the right.
Continued periodic checks of the propane system periodically (or at least once a year), by a
qualied propane service representative as part of your normal maintenance is recommended.
Hand tighten the propane gas system valves only, do not use a wrench or pliers as over
tightening may damage the valve seals and cause them to leak.
Propane Leak Test
Leaks may be found easily with a soapy water solution. Do not use a solution containing
ammonia or chlorine when locating leaks. ese products are corrosive to copper gas lines
and brass ttings, which could result in deterioration of the copper and brass components.
Apply the soapy solution to the outside of the gas piping ttings. If a leak is present, the soapy
solution will “bubble” at the leak point. If a leak is indicated, shut OFF the propane system
valve(s) and contact a your selling dealer’s service department or qualied propane service
representative immediately.
Propane Gas Tank
PROPANE SYSTEM
WARNING
Do not ll propane container(s) to more than 80 percent of capacity. A properly lled
container contains approximately 80 percent of its volume as liquid propane.
Overlling the propane container(s) can result in uncontrolled propane ow, which
could lead to a re or explosion and result in death or serious injury.
WARNING
If you suspect your propane container has been overlled, contact your selling
dealer or a qualied propane technician for assistance immediately. Do not attempt
to service a propane container overll yourself.
NOTE: Propane tanks are to be installed,
fueled, and maintained in accordance to
country, federal, state, and local codes,
rules, regulations, laws, or guidelines.

WARNING
Always shut OFF the engine while refueling propane tank. Do not smoke and do not
operate other ignition sources while refueling.
A permanently mounted A.S.M.E. (American Society of Mechanical Engineers) approved
propane container is located under the oor of your motorhome. Propane expands 1½ percent
for every ten degrees of increase in temperature. It is imperative to leave sucient space inside
the container to allow for natural expansion of gas during warmer weather.
Servicing or Filling
Because the propane tank is not removable, the motorhome will need to be driven to a
qualied propane facility for servicing or lling. Only the authorized gas service technician(s)
should be near the motorhome while the propane tank is being lled. e new propane
container must be carefully purged for proper appliance performance and operation. e
propane tank must NEVER BE OVERFILLED.
Never allow your propane tank to be lled above the maximum safe level as indicated by the
xed liquid level gauge. Do not allow the visible gauge to be used for lling. Overlling the
propane container above the liquid capacity indicated on the container, could allow liquid
propane to enter the system that is designed for vapor only creating a hazardous condition.
e following warning label has been placed on the propane tank:

Using the Propane System
After your motorhome is completely set up, to operate the propane system:
1. Close ALL burner valves, controls and pilot light valves.
2. Open the main valve in the propane tank slowly to avoid a fast rush of propane vapor
through the excess ow valve causing propane “freeze-up.” If you experience propane
“freeze-up,” close the main valve and wait 15 minutes before trying again.
3. Listen carefully as propane begins to ow. If a hissing noise is heard for more than one or
two seconds, close the main valve and contact your selling dealer’s Service Department to
have the propane system tested.
4. Light the appliances as needed and directed in the appropriate appliance manufacturer
instructions.
Make sure that you read and fully understand ALL safety requirements for handling and
operation of the propane system.

Water Systems
Fresh Water System
Potable (drinking) water is supplied throughout your motorhome from the fresh water tank
or from a connection to an outside water source attached to the city water ll. When using
the fresh water tank, water is pressurized and travels through the water lines by means of the
water pump. When utilizing an exterior water source, such as a campsite water spigot, the
water pump is not needed as the campsite water source is already pressurized and will ow
through the water supply lines.
Potable Water Hose
We recommend purchasing and keeping sanitized a water hose whose sole function is for use
with your potable water system. We do not recommend using the same water hose for potable
water, maintenance, or sewer system cleanup, etc.

lines and to the water heater. When ready, gradually open the hot and cold water at the sinks
and tub to clear air from the lines (it can be normal to see water "spit" from the faucets until
the system is pressurized). Close the faucets when the water is owing freely.
Water Pump
When you are not connected to city water (e.g., campsite water) and want to use water in your
motorhome you will need sucient 12 volts DC power to run the water pump. Once turned
ON at the monitor panel, the water pump (also known as an on-demand pump) will selfprime and provide water.
OPERATION
e water pump is designed for use on an as needed basis. Using the water pump continuously
or with high pressure will shorten its operational life and is not covered by warranty. e
water pump has a check valve that prevents water from back owing into the fresh water tank.
Before operating the water pump:
1. Make sure there is adequate water in the fresh water tank.
2. Be sure the water heater bypass valves are set correctly according to your water system
label.
WATER SYSTEMS
NOTE: Do not turn the water pump ON
if the fresh water tank is empty. Doing so
could cause damage to the water pump, or
blow a fuse.
NOTE: Do not turn ON the water pump
when using water from an external source.
Only run the water pump if using potable
water stored in your fresh water tank.
NOTE: The water pump should be
turned OFF when the motorhome is left
unattended for any amount of time. This
may help limit potential damage should
something fail within the water system.
3. Open all the faucets (rst hot, then cold) including your interior and exterior shower

Waste Water System
Depending on your motorhome model year, make, and model, the water and debris from the
sinks and shower (or tub) ow into the gray water (or waste water) holding tank. Water and
debris from the toilet ow into the black water (or sewage) holding tank. Some brands and
models may also have the lavatory, shower, or tub draining into the black water (waste water)
holding tank.
Drain Pipes
WATER SYSTEMS
Drain pipes have P-traps and/or waterless traps (HEPVOs) installed to help prevent drain
odors from escaping into the motorhome. During travel, water within P-traps may displace
and permit odors into the motorhome. Drain-related odors come from decomposing
materials in the holding tank. If odors are detected, place a few cups of water down each drain
and use a RV approved deodorizing agent, which will reduce drain odors and help keep the
drain lines and tanks clean and free owing. Drain chemicals are available at RV supply stores.
Vents
Vent pipes and vents release air from the grey and black water holding tanks. e exterior
vent cap is attached to the roof, and must be kept clear of debris and obstructions to perform
as intended. On some brands and models, the vent pipe may be part of the drainage system
referred to as a “wet vent” (water ows downward as air ows upward in the same pipe).
Emptying the Holding Tanks
