Gross Combined Weight Rating (GCWR)
GCWR is the total allowable weight of the
completely loaded vehicle and trailer
including any fuel, passengers, cargo,
equipment, and accessories. Do not exceed
the GCWR for your vehicle. The GCWR for
the vehicle is on the Tow Rating Chart
following.
To check that the weight of the vehicle and
trailer are within the GCWR for the vehicle,
follow these steps:
Start with the "curb weight"
Add the weight of the trailer loaded with
cargo and ready for the trip
Add the weight of all passengers
Add the weight of all cargo in the vehicle
Add the weight of hitch hardware such as
a draw bar, ball, load equalizer bars,
or sway bars
Add the weight of any accessories or
aftermarket equipment added to the
vehicle
The resulting weight cannot exceed the
GCWR value.
The gross combined weight can also be
confirmed by weighing the truck and trailer
on a public scale. The truck and trailer
should be loaded for the trip with
passengers and cargo.
Driving and Operating

maximum load capacity, see Vehicle Load

with a trailer attached, the trailer tongue
weight must be included as part of the
weight the vehicle is carrying.
Maximum Trailer Weight
Use the tow rating chart to determine how
much the trailer can weigh, based on the
vehicle model and options.
