Gross combined weight rating
The gross combined weight rating or gross combination weight rating (GCWR), also referred to as the gross combination mass (GCM), gross train weight (GTW), is the maximum allowable combined mass of a road vehicle, the passengers and cargo in the tow vehicle, plus the mass of the trailer and cargo in the trailer.[1][2] This rating is set by the vehicle manufacturer.
The GCWR is a function of the torque output of the engine, the capacity and ratios of the transmission, the capacity of the driving axles and tires, the capacity of the radiator, and the ability of the chassis to withstand that powertrain torque.
