(a) The Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle
and trailer including any passengers, cargo, equipment, and conversions. The GCWR for the vehicle should not be
exceeded.
(b) This model is neither designed nor intended to tow fifth-wheel or gooseneck trailers.
(c) For pickup box delete vehicles, choose an appropriate hitch and load the truck and trailer within the limits of
GCWR, GVWR, and RGAWR.
(d) Maximum Trailer Weight cannot be provided because total vehicle weight is unknown.
Ask your dealer for trailering
information or advice.
Weight of the Trailer Tongue The tongue load (1) of any trailer is
very important because it is also
part of the vehicle weight. The
Gross Vehicle Weight (GVW)
includes the curb weight of the
vehicle, any cargo carried in it, and
the people who will be riding in the
vehicle as well as trailer tongue
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.

Mexico-9955992) - 2017 - crc - 4/18/17
Driving and Operating 339Trailer tongue weight (1) should be
10-15% and fifth-wheel or
gooseneck kingpin weight should be
15-25% of the loaded trailer
weight (2) up to the maximums for
vehicle series and hitch type. Vehicle Series Hitch Type Maximum Tongue

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.
Trailer rating 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.
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.

340 Driving and Operating If a cargo carrier is used in the
trailer hitch receiver, choose a
carrier that positions the load as
close to the vehicle as possible.
Make sure the total weight,
including the carrier, is no more than
half of the maximum allowable
tongue weight for the vehicle or
227 kg (500 lb), whichever is less.
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 center pillar or see Vehicle
Load Limits 0 265 . 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. Weight of the Trailering
Combination It is important that the combination
of the tow vehicle and trailer does
not exceed any of its weight ratings
— GCWR, GVWR, RGAWR, Trailer
Weight Rating, or Tongue Weight.
The only way to be sure it is not
exceeding any of these ratings is to
weigh the tow vehicle and trailer
combination, fully loaded for the trip,
getting individual weights for each of
these items.
Towing Equipment Hitches The correct hitch equipment helps
maintain combination control. Many
trailers can be towed with a
weight-carrying hitch which simply
features a coupler latched to the
hitch ball, or a tow eye latched to a
pintle hook. Other trailers may
require a weight-distributing hitch
that uses spring bars to distribute
the trailer tongue weight among the
tow vehicle and trailer axles. Fifth-wheel and gooseneck hitches
may also be used. See “ Weight of
the Trailer Tongue ” under Trailer
Towing 0 323 for rating limits with
various hitch types.
If a step-bumper hitch will be used,
the bumper could be damaged in
sharp turns. Make sure there
is ample room when turning to avoid
contact between the trailer and the
bumper.
Consider using sway controls with
any trailer. Ask a trailering
professional about sway controls or
refer to the trailer manufacturer's
recommendations and instructions.
Weight-Distributing Hitch and
Adjustment A weight-distributing hitch may be
useful with some trailers. Use the
following guidelines to determine if a
weight-distributing hitch should
be used.
