GVWR stands for Gross Vehicle Weight Rating and represents the maximum weight a trailer is designed to carry, including the trailer’s own weight and the weight of any cargo. It is determined by the manufacturer and can be found on the trailer’s VIN Sticker, which is usually located on the tongue or front of the trailer.Payload is the weight of the cargo and any additional equipment that a trailer can legally carry. It is calculated by subtracting the trailer’s empty weight from the GVWR. For example, if a vehicle has a GVWR of 10,000 pounds, and an empty weight of 3,000 pounds, then its payload capacity would be 7,000 pounds.
