Weight of the Trailer How heavy can a trailer safely be? It should never weigh more than 1,400 lbs. (630 kg) with up to six occupants in the vehicle or more than 2,000 lbs. (900 kg) with up to two occupants. If you have the optional trailer towing package, your vehicle can tow up to 2,900 lbs. (1 300 kg) with up to six occupants or up to 3,500 lbs. (1 575 kg) with up to two occupants. If you have the Thunder, your vehicle can tow up to 2,600 lbs. (1 180 kg) with up to six occupants or up to 3,200 lbs. (1 410 kg) with up to two occupants. But even that can be too heavy. 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.
