GUIDELINES FOR MATCHING HITCH TRUCK AND TRAILER
WARNING:
Failure to check and follow tow ratings could result in tow vehicle
damage or truck and trailer separation while towing.
•Trailer and its contents together must not exceed truck, hitch and/or trailer tow
ratings.
•Towing vehicle must have a manufacturer’s rated towing capacity equal to or
greater than the gross trailer weight (dry weight of the trailer plus payload of the
trailer). (Figure 2)
•Gross weight of trailer must not exceed fifth wheel hitch rating.
•King pin weight must not exceed fifth wheel rating (Figure 3). If in doubt have king
pin weight measured by a qualified technician.

1. Maximum Gross Trailer Weight of : 18,000 lb / 8160kg.
Vehicle tow rating: _______________.
Total calculated Gross Trailer Weight (Figure 2):______________.
*Trailer weight should be the lowest of these recorded ratings for safe towing conditions.
2. Cequent Towing Products hitches are designed for use with recreational fifth wheel trailers only. Hitch applications other than
recreational fifth wheel trailers must be approved in writing by Cequent Towing Products’ Engineering Department.
3. Use only a SAE 2-inch kingpin with your Signature Series Fifth Wheel Hitch.
4. Approximately 15%-25% of trailer weight should be on hitch (Pin Weight)(Figure 3).
5. Trucks come in many different configurations. Cequent Towing Products’ hitches are designed for use in light trucks such as the
Ford F-Series, the Chevy Silverado and the Dodge Ram. Cequent Towing Products recommends the use of long bed (8ft) light
trucks for the best combination in truck - trailer turning clearance.
Rule of thumb:The distance from the back of the truck cab to the center of the rear truck
axle (“X” in Figure 4), should be approximately 4 inches greater than one-half
the trailer width (“Y” in Figure 4)

6. If a short bed pickup (less than 8 ft. but longer than 6 ft.) is to be used for towing, Cequent Towing Products recommends the
trailer be equipped with an extended pin box to help gain additional truck - trailer turning clearance (See trailer manufacturer for
options) (Figure 5). It also may be helpful to add a
speed, non-highway maneuvering.

WARNING:
Do Not install this fifth wheel hitch on or attempt to tow with a short bed pickup
truck that has a bed shorter than 6 ft.!
7. The height of the hitch and the pin box should be adjusted so the trailer is approximately level as it is towed. Allow
approximately 6 inches clearance between the top of the pickup walls and the underside of the front of the trailer for pitch and
roll of the trailer. (Figure 6). Allow more clearance between pickup walls and trailer for off road use.

Approximately 6 Inches
Level Trailer
CAUTION:
The measurements above are guidelines. If your measurements are close to these numbers re-check clearances. If
vehicle and/or trailer has any added bed vicinity accessories (i.e. fairings, air dams, ground effects, bed rails, etc.).
Additional dimensioning and clearance checks have to be made.
8. Hitch height determination:
With trailer leveled and on level ground measure from the ground to the king pin box (“A” in Figure 7). Secondly measure from
the height of the inside of the truck bed (“B” in Figure 7). Determine the amount of clearance over the side rails ( “C” and “D” in
Figure 7), as mentioned in Note 7.
Hitch Height = A – B + 2”
The 2” value is an estimate of suspension compression due to king pin weight of the trailer. This compression could range
between 1”-5” depending on the truck being used and the trailer being towed.
D – C + 2” > 6” as in Note 7.

9. If a lube plate is to be used with a Signature Series 5thWheel it must be at least 12” in diameter. Cequent Towing Products offers
this optional lube plate as part # 83001 / 40001.

WARNING:
•Connection for trailer wiring must be located at the side of the truck bed between the driver’s
seat and the rear wheel to prevent operators from working between the truck and trailer.
•Avoid putting any part of your body under the trailer or between the truck and trailer.
Unexpected or accidental movement of the truck or the trailer can cause serious injury or death
•If you must place any part of your body under the trailer or between the truck and trailer you
MUST
perform ALL of the following steps:
•Check that the truck transmission is in park
•Check that the emergency brake is on
•Block in front of and behind all trailer tires
•Check that the trailer landing gear are resting on firm ground
