Check the hitch rating label for correct maximum for the vehicle.
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.

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.
Be sure the vehicle's tires are
inflated to the inflation pressures
found on the Certification Tire label
on the driver door or see
information. Make sure not to
exceed the GVWR limit for the
vehicle, or the RGAWR, with the
tow vehicle and trailer fully loaded
for the trip including the weight of
the trailer tongue. If using a
weight-distributing hitch, make sure
not to exceed the RGAWR before
applying the weight distribution
spring bars.
