Fifth Wheel Landing Legs Operation
The landing legs of the trailer are intended for positioning
the RV during hook-up and unhooking from the tow
vehicle. The landing legs also support the trailer during
camping and storage. The legs are not designed for the
sole support of the fifth wheel weight during tire changes
or servicing.
CAUTION
THE LANDING LEG WEIGHT RATING IS 3,500 LBS. PER LEG. DO NOT
EXCEED THE WEIGHT RATING.
Note
THE LEGS MAY BIND IN OVERLOAD CONDITIONS.
THIS WILL RESULT IN PREMATURE WEAR OF
THE DRIVE GEAR AND STRIPPING OF THE GEAR.
PREMATURE GEAR WEAR WILL ALSO OCCUR
WITH EXCESSIVE CLUTCHING OF THE MOTOR.
THIS OCCURS AT MAXIMUM EXTENSION AND
RETRACTION. ONCE CLUTCH NOISE IS HEARD,
RELEASE THE SWITCH.
TO LOWER LEGS WITH ELECTRIC or HYDRAULIC MOTOR:
Push the switch, located at the front of the trailer, to the
extend position and hold until the landing legs raise the
vehicle to the desired height. Extend and retract indicate
the travel direction of the legs, not the fifth wheel.
TO RAISE LEGS WITH ELECTRIC or HYDRAULIC MOTOR:
Push the switch, located at the front of the trailer,
to the retract position and hold until the legs are fully
retracted. Release the toggle switch as the lock pins
in the landing legs near the end of the outside tubes to
avoid unnecessary wear on the motor clutch.
Note
LANDING LEGS MAY WORK WITH HANDLE IF THE
ELECTRIC DRIVE MOTOR IS INOPERATIVE OR IF
ELECTRICITY IS UNAVAILABLE.
WARNING
REMOVE THE HANDLE BEFORE USING THE ELECTRIC MOTOR; THE
HANDLE MAY JERK, CAUSING INJURY. BEFORE TOWING, CHECK FOR
MAXIMUM CLEARANCE BETWEEN THE GROUND AND THE BOTTOM OF
THE LANDING GEAR.
TO LOWER LEGS MANUALLY:
Insert the crank handle into the alignment tube until
the end engages the crank shaft. The shaft is located
at the front of the trailer. Turn the crank handle
counterclockwise to raise vehicle to the desired height.
Remove and store the handle.
TO RAISE LEGS MANUALLY:
Insert the crank handle into the alignment tube until the

Stabilizer Jacks
Stabilizing jacks, located at the rear corner on the
trailer are permanently attached and operated from a
standing position. These jacks are for stabilizing only.
Primary leveling should be done with wheel ramps and
front landing legs. Lower the stabilizing jacks until they
contact the ground firmly. Place wooden blocks under
the pads if necessary.

UNEVEN GROUND OR TO CHANGE TIRES. NEVER USE JACK(S) TO
ELEVATE ANY WHEEL OFF THE GROUND. DAMAGE TO THE STABILIZER
