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. 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.
