Three important considerations have to do with weight: In Canada, write to: General Motors of Canada Limited Customer Communication Centre, 163-005 1908 Colonel Sam Drive Oshawa, Ontario L1H 8P7 D the weight of the trailer, D the weight of the trailer tongue D and 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 1,000 lbs. (450 kg) including the cargo, passengers and equipment. 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. Box 33172 Detroit, MI 48232-5172 Weight of the Trailer Tongue The tongue load (A) of any trailer is an important weight to measure because it affects the total or gross weight of your vehicle. 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. And if you 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" in the Index for more information about your vehicle's maximum load capacity. 4-34
