When using a weight-distributing

hitch, measure distance (1) before

coupling the trailer to the hitch ball.

Measure the height again after the

trailer is coupled and adjust the

spring bars so the distance (1) is as

close as possible to halfway

between the two measurements.

Fifth-wheel and gooseneck trailers

can be used with many pickup

models. These trailers place a

larger percentage of the weight

(kingpin weight) on the tow vehicle

than conventional trailers. Make

sure this weight does not cause the

vehicle to exceed GAWR or GVWR.

Fifth-wheel or gooseneck kingpin

weight should be 15 to 25 percent of

the trailer weight up to the maximum

amount specified in the trailering

chart for the vehicle. See Weight of

the Trailer under

The hitch should be located in the

pickup bed so that its centerline is

over or slightly in front of the rear

axle. Take care that it is not so far
