When using a weight-distributing
hitch, measure distance (A) before
coupling the trailer to the hitch ball.
If the hitch requires 50%
distribution, measure the height
again after the trailer is coupled and
adjust the spring bars so the
distance (A) is as close as possible
to halfway between the two
measurements. When 100%
distribution is required the spring
bars should be adjusted so the
distance (A) is the same as the

Fifth-wheel and gooseneck trailers

(kingpin weight) on the tow vehicle
than conventional trailers. Make
sure this weight does not cause the
vehicle to exceed GAWR or GVWR.
