Measuring Height (H)
3. Attach the trailer to the vehicle without the weight distri-
bution bars connected.
4. Measure the height of the top of the front wheel opening
on the fender to ground, this is height H2.
5. Install and adjust the tension in the weight distributing
bars per the manufacturers’ recommendations so that the
height of the front fender is approximately (H2-H1)/
2+H1 (about 1/2 the difference between H2 and H1 above
normal ride height [H1]).
6. Preform a visual inspection of the trailer and weight
distributing hitch to confirm manufacturers’ recommen-
dations have been met.
NOTE:
For all towing conditions, we recommend towing with tow
haul mode engaged.
Fifth-Wheel Hitch
The fifth-wheel hitch is a special high platform with a
coupling that mounts over the rear axle of the tow vehicle in
the truck bed. It connects a vehicle and fifth-wheel trailer
with a coupling king pin.
Your truck may be equipped with a 5th wheel hitch option.
Refer to the separately provided 5th wheel hitch safety, care,
assembly, and operating instructions.
