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
the GVWR (Gross Vehicle Weight
Rating) or the RGAWR (Rear Gross
Axle Weight Rating). See “Total
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.
Total Weight on the Vehicle's
Tires
Be sure the vehicle's tires are
inflated to the inflation pressures
found on the Certification Tire label
on the drivers door or see Vehicle
Load Limits on page 9‑25 for more
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.
