weight. Vehicle options, equipment,
passengers, and cargo in the
vehicle reduce the amount of
tongue weight the vehicle can carry,
which will also reduce the trailer
weight the vehicle can tow. See
Vehicle Load Limits on page 9 23
for more information about the
vehicle's maximum load capacity.
Trailer tongue weight (A) should be 10 percent to 15 percent and fifth-wheel
or gooseneck kingpin weight should be 15 to 25 percent of the loaded trailer
weight up to the maximums for vehicle series and hitch type shown here:

Do not exceed the maximum
allowable tongue weight for the
vehicle. Choose the shortest hitch
extension that will position the hitch
ball closest to the vehicle. This will
help reduce the effect of trailer
tongue weight on the rear axle.
Trailering may be limited by the
vehicle's ability to carry tongue
weight. Tongue or kingpin weight
cannot cause the vehicle to exceed

Weight on the Vehicle's Tires later
in this section for more information.
After loading the trailer, weigh
the trailer and then the tongue,
separately, to see if the weights are
proper. If they are not, adjustments
might be made by moving some
items around in the trailer.
