The weight of the trailer tongue. The total weight on your vehicle's tires. Weight of the Trailer How heavy can a trailer safely be? It should never weigh more than 454 kg (1,000 lbs). But even that can be too heavy. It depends on how the rig is used. For example, speed, altitude, road grades, outside temperature and how much the vehicle is used to pull a trailer are all important. It can depend on any special equipment on the vehicle, and the amount of tongue weight the vehicle can carry.

The Gross Vehicle Weight (GVW) includes the curb weight of the vehicle, any cargo carried in it, and the people who will be riding in the vehicle.
