Towing Motor Home - GMC Motor Home Operating Manual

Jacking at Rear of Motor Home
CAUTION
Use lug wrench provided to tighten
wheel nuts securely . (Follow the nut
tightening sequence shown in the SER-
VICE AND MAINTENANCE section) . At
the earliest opportunity have wheel nut
torque checked . This is necessary to help
prevent loosening or stripping of the
wheel nuts .
TOWING MOTOR HOME
Proper lifting or towing equipment is neces-
sary to prevent damage to the GMC Motor
Home during any towing operation . State (Pro-
vincial in Canada) and local laws applicable to
vehicles in tow must also be followed. Motor
Home service outlets can advise you on the
selection of a knowledgeable towing concern .
Your Motor Home may be towed on all six
wheels at speeds of less than 35 MPH, for dis-
tances up to 50 miles, provided final drive, axle,
and transmission are otherwise normally oper-
able. For such towing, parking brake must be
released, transmission must be in neutral, and
the ignition key turned to OFF position .

TOWING AT FRONT
NOTE : Attachments must be to frame front
crossmember of the Motor Home, not to bump-
ers or bracketing. Separate safety chains or
cables should be used. Care must be taken in
installation of chains to ensure that they do not
cause damage. Remember that power brake and
steering assists will not be available when engine
is inoperative .
Certain other precautions are required when
it is necessary to tow with the front drive wheels
lifted off the road . On Motor Homes equipped
with the Power Level System, turn the valve
dials, below the instrument panel, to "LOCK"
position, thereby making the automatic height
valves inoperative on the rear suspension . On
Motor Homes not equipped with the optional
Power Level System it will be necessary to dis-
connect the height control valve link arm at the
rear suspension control arm (adjacent to the
shock absorber stud) on each side of the vehicle.
Raising front of vehicle so front wheels are four
inches off the ground will provide about five-
inch ground clearance at the rear when towing .
TOWING AT REAR
It is not recommended that vehicle be towed
with the rear raised as this could result in sus-
pension or crossmember damage .
