Tires
Do not tow a trailer while using a
compact spare tire on the vehicle.
Tires must be properly inflated to support
loads while towing a trailer. See Tires
0 321 for instructions on proper tire
inflation.
Fifth-Wheel and Gooseneck Trailering
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
Gross Axle Weight Rating (GAWR) or Gross
Vehicle Weight Rating (GVWR). Fifth-wheel
or gooseneck kingpin weight should be
15 25% of the trailer weight up to the
H1
H2
maximum amount specified in the trailering
chart for the vehicle. See Trailer Weight"
under Trailer Towing 0 267.
The hitch should be in the pickup bed so
that its centerline is over or near the rear
axle. Take care that it is not so far forward
that it will contact the back of the cab in
sharp turns. This is especially important for
short box pickups. Trailer pin box extensions
and sliding fifth-wheel hitch assemblies may
be used. There should be at least 15 cm
(6 in) of clearance between the top of the
pickup box and the bottom of the trailer
shelf that extends over the box.
Attach the hitch to the tow vehicle frame
rails. Do not use the pickup box for support.

Always attach safety chains between the

manufacturer or by the trailer manufacturer.

2 271 kg (5,000 lb) with a factory-installed
