Cutaway: Gross Combination Weight Rating (GCWR) Engineers perform extensive
testing of acceleration, handling, braking, and thermal and structural performance
to determine the GCWR for your vehicle. The GCWR is the total allowable weight
of the completely loaded vehicle and trailer including any passengers, cargo,
equipment and conversions. You should not exceed the GCWR of your vehicle when
you tow a trailer.
