1. Position the truck to be ready to connect to
the trailer (do not connect the trailer).
NOTE:
Normal Ride Height (NRH) or Alternate Trailer
Height (ATH) can be used. The vehicle must
remain in the engine running position while
attaching a trailer for proper leveling of the air
suspension system. It may not be possible to enter
Alternate Trailer Height (ATH) while lightly loaded.
2. Measure the height of the top of the front
wheel opening on the fender to ground, this
is height H1.
3. Attach the trailer to the vehicle without the
weight distribution 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’ recommendations have
been met.
Weight distributing systems may not be
compatible with surge brake couplers.
Consult with your hitch and trailer manufac
-
turer or a reputable Recreational Vehicle
dealer for additional information.
