System and Safety Information
Failure to act in accordance with the following may result in death or serious personal injury. The use of
the Ground Control 3.0 leveling system to support the unit for any reason other than which it is intended
is prohibited by Lippert’s limited warranty. The Lippert leveling system is designed as a “leveling”
system only and should not be used to provide service for any reason under the coach such as changing
tires or servicing the leveling system. Any attempts to change tires or perform other service while unit
is supported by the Ground Control 3.0 leveling system could result in damage to the 5th wheel and/or
cause death or serious injury.
Be sure to park the unit on solid, level ground. Clear all jack landing locations of debris and obstructions.
Locations should also be free of depressions. When parking the unit on extremely soft surfaces, utilize
load distribution pads under each jack. People and pets should be clear of coach while operating leveling
system. Never lift the unit completely off the ground. Lifting the unit so the wheels are not touching the
ground will create an unstable and unsafe condition.

Ground Control 3.0 OEM Installation Manual
Preparation
1. Remove all loose items from the front storage compartments of the 5th wheel.
2. Analyze the unit. Determine where the rear jack brackets, controller, and touch pad will be mounted
on the unit. The rear jack brackets should be mounted approximately 1 foot behind the rear axle
hanger and be aligned with each other. The controller should be mounted in the center of the unit
in compliance with RVIA Gas Codes as the controller connections are not spark-proof. The touch pad
should be mounted in a compartment on the side of the unit so that the operator will have a view of
the hitch pin while using the touch pad. The touch pad MUST also be protected from the elements.
NOTE: The landing gear will be installed to the frame of the unit by LCI.
Installation - Rear Jacks
1. Determine position and ground clearance requirements for the rear jacks (Fig. 1D). The rear jack
brackets (Fig. 1C) should be mounted approximately 1 foot behind the rear axle hanger and be aligned
with each other.
NOTE: When fully retracted, rear jacks should be equal to the departure angle or a minimum of 7" of ground
clearance.
2. Mark jack mounting bracket (Fig. 1C) locations on the main frame rail.
3. Clamp the bracket to the main frame rail (Fig. 1B) in the marked position.
4. Weld the bracket to the main frame rail (Fig. 1B).
5. Bolt the rear jacks (Fig. 1D) to the mounting brackets (Fig. 1C) using six bolts (Fig. 1E) and nuts (Fig. 1A)
per jack. Tighten the bolts to 90 lb.-ft. of torque.
6. Connect the wire harnesses to the rear jack motor wires and run the harnesses to the compartment
where the controller will be mounted.
NOTE: LCI recommends zip-tying the harnesses tight against the rear jack motors to prevent damage to the
harnesses.

Installation - Rear Sensor
The rear sensor (Fig. 2A) MUST be installed on the crossmember to the rear of the back axle, centered curbside to
roadside on the unit with the arrows on the top of the sensor pointing the correct direction (Fig. 2 detail).

1. Dry fit the mounting plate (Fig. 3A) and the rear sensor (Fig. 3B) to the crossmember (Fig. 3C). The pre-
drilled holes in the plate are for mounting the rear sensor to the plate. Mark on the plate where the rear
sensor will set. Space between the sensor and the crossmember MUST be left so the wire harness will
not be pinched.

2. Attach the rear sensor (Fig. 4B) to the mounting plate (Fig. 4C) using two ⁄" hex head self-tapping
screws (Fig. 4A). Orientation is imperative for the correct operation of the leveling system.

3. Attach the mounting plate (Fig. 5B) and sensor (Fig. 5C) assembly to the crossmember (Fig. 5D) using
two ⁄" hex head self-tapping screws (Fig. 5A). Ensure that the plate is centered side to side on the
frame and that the sensor is oriented properly (Fig. 5).
