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. Use the following chart to determine how much your vehicle can weigh, based upon your vehicle model and options. Notice: Using a fifth-wheel or goose-neck hitch device on your vehicle could damage the vehicle. The repairs would not be covered by your warranty. Do not use a fifth-wheel or goose-neck hitch device on your vehicle.
