Driving and Operating
Maximum Trailer Weight
The maximum trailer weight rating is
calculated assuming the tow vehicle has a
driver, a front seat passenger, and all
required trailering equipment. This value
represents the heaviest trailer the vehicle
can tow, but it may be necessary to reduce
the trailer weight to stay within the GCWR,
GVWR, maximum trailer tongue load,
or GAWR-RR for the vehicle.
Use the Tow Rating Guide (my.gmc.com/
learn) to determine how much the trailer
can weigh, based on the vehicle model and
options.
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.
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.
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 your vehicle, hitch, and
trailer.
