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 five 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 five occupants or up to 3,500 lbs (1 575 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. You can ask your dealer for our trailering information or advice, or you can write us at: Pontiac-GMC Customer Assistance Center P.O.

The Gross Vehicle Weight (GVW) includes the curb weight of the vehicle, any cargo you may carry in it, and the people who will be riding in the vehicle. If you have a lot of options, passengers, or cargo in the vehicle, it will reduce the tongue weight your vehicle can carry, which will also reduce the trailer weight your vehicle can tow. And if you will tow a trailer, you must add the tongue load to the GVW because your vehicle will be carrying that weight, too. See Loading Your Vehicle on page 4-31 for more information about your vehicle's maximum load capacity. 4-40
