Gross Combination Weight Rating (GCWR) is the absolute maximum weight limit specified by the manufacturer for a fully loaded vehicle and its attached trailer. This rating ensures the engine, transmission, cooling system, and brakes can safely accelerate, control, and stop the combined mass. Exceeding the GCWR risks severe drivetrain damage and catastrophic brake failure on downgrades.
