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. And, it can also depend on any
special equipment that you have on your vehicle.

Use one of the following charts to determine how much
your vehicle can weigh, based upon your vehicle model
and options.

Maximum trailer weight is calculated assuming the
driver and one passenger are 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.

Above the 5,000 lbs. (2 268 kg) trailer rating, the
handling/trailering suspension is required on
C

-

1500 models and the handling/trailering or off

-

road

suspension is required on K

-

1500 models. The engine

oil cooler is required on C/K

-

2500 models with the

VORTEC 6000 engine. Refer to the Trailering Guide for
oil cooler recommendations.

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.
