GMC Sierra 2500 HD 2024 Owner's Manual page 285

Use the Trailering Information Label to
determine how much the trailer can weigh.
Weights listed apply for conventional trailers
and gooseneck/fifth-wheel trailers unless
otherwise noted.
A step bumper trailer hitch can only support
a total trailer weight up to 2 271 kg
(5,000 lb). If a trailer hitch ball is added to
the step bumper, check the hitch ball rating
to be sure it is higher than the total trailer
weight.
Maximum Trailer Tongue Weight Rating
The Maximum Trailer Tongue Weight Rating
is the allowable trailer tongue weight that
the vehicle can support using a conventional
trailer hitch. It may be necessary to reduce
the overall trailer weight to stay within the
maximum trailer tongue weight rating while
still maintaining the correct trailer load
balance. A fifth-wheel or gooseneck hitch
may support a higher tongue weight.
The Maximum Trailer Tongue Weight Rating
for a conventional trailer hitch or a fifth
wheel/gooseneck hitch is shown on the
Trailering Information Label.
Do not exceed a maximum trailer tongue
weight of 907 kg (2,000 lb) for a
conventional trailer hitch.
The trailer tongue weight contributes to the
Gross Vehicle Weight (GVW). GVW includes
the curb weight of your vehicle, any
passengers, cargo, equipment and the trailer
tongue weight. Vehicle options, passengers,
cargo, and equipment reduce the maximum
allowable tongue weight the vehicle can
carry, which also reduces the maximum
allowable trailer weight.
Driving and Operating
Trailer Load Balance
The correct trailer load balance must be
maintained to ensure trailer stability.
Incorrect load balance is a leading cause of
trailer sway.
The trailer tongue weight (1) should be
10 15% and fifth-wheel or gooseneck tongue
weight should be 15 25% of the total loaded
trailer weight (2). Some specific trailer types,
such as boat trailers, fall outside of this
range. Always refer to the trailer owner s
manual for the recommended trailer tongue
weight for each trailer. Never exceed the
maximum loads for the vehicle, hitch, and
trailer.
