Weight of the Trailer
How heavy can a trailer safely be?
It depends on how you plan to use your rig. For
example, speed, altitude, road grades, outside
temperature and how much your vehicle is used to
pull a trailer are all important. It can also depend
on any special equipment that you have on
your vehicle, and the amount of tongue weight the
vehicle can carry. See “Weight of the Trailer
Tongue” later in this section for more information.
Maximum trailer weight is calculated assuming
only the driver is in the tow vehicle and it has all
the required trailering equipment. The weight
of additional optional equipment, passengers and
cargo in the tow vehicle must be subtracted
from the maximum trailer weight.
The following charts show how much your trailer
can weigh, based upon your vehicle model
2WD Extended Cab Axle Ratio Maximum Trailer Weight GCWR*
2.9 L Engine 3.73 3,100 lbs (1 406 kg) 7,000 lbs (3 175 kg)

4WD Crew Cab Axle Ratio Maximum Trailer Weight GCWR*
3.7L Engine 3.73 4,000 lbs (1 814 kg) 9,000 lbs (4 082 kg)
*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 your
vehicle should not be exceeded.
