The Gross Combined Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle and trailer including passengers,
cargo equipment and conversions. The GCWR for the vehicle should not be exceeded.
(1) Maximum Trailer Weight cannot be provided because total vehicle weight is unknown.
(2)
All 4.56 / 4.88 / 4.30 ratios with a GCWR ratio of 34,000 lb, 35,000 lb, or 37,000 lb, require a 15,000 lb or 15,500 lb rated rear axle.
(3)
Choose an appropriate hitch and load the truck and trailer within the limits of GCWR, GVWR, and RGAWR.
(4) With a rear axle less than 15,000 lb.
Trailer Tongue Weight
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.
Transmission Axle Ratio (2)
The trailer tongue weight (1) should be 10
15% and fifth-wheel or gooseneck kingpin
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
Driving and Operating
Maximum Trailer
Weight (3)
manual for the recommended trailer tongue
weight for each trailer. Never exceed the
maximum loads for your vehicle, hitch and
trailer.
The trailer load balance percentage is
calculated as: weight (1) divided by
weight (2) times 100.
After loading the trailer, separately weigh
the trailer and then the trailer tongue and
calculate the trailer load balance percentage
to see if the weights and distribution are
appropriate for your vehicle. If the trailer
weight is too high, it may be possible to
transfer some of the cargo into your vehicle.
If the trailer tongue weight is too high or
too low, it may be possible to rearrange
some of the cargo inside of the trailer.
