GVWR stands for Gross Vehicle Weight Rating, which is the maximum allowable weight of a vehicle or trailer as determined by the manufacturer. This weight includes not only the weight of passengers and cargo, but also the weight of the vehicle or trailer itself. The GVWR is determined by taking into consideration the suspension system, frame, axles, wheels, and other components bearing the load. It is an important safety rating, as exceeding the GVWR can cause damage to the vehicle or trailer, as well as create a safety hazard on the road. The GVWR can be found on a label placed inside the drivers door jamb.
