So what do these weight abbreviations mean?


The gross vehicle weight rating (GVWR), or gross vehicle mass (GVM) is the maximum operating weight/mass of a vehicle as specified by the manufacturer including the vehicle’s chassis, body, engine, engine fluids, fuel, accessories, driver, passengers, and cargo but excluding that of any trailers. The term is used for motor vehicles and trains.

The weight of a vehicle is influenced by passengers, cargo, even fuel level, so a number of terms are used to express the weight of a vehicle in a designated state. Gross combined weight rating (GCWR) refers to the total mass of a vehicle, including all trailers. GVWR and GCWR both describe a vehicle that is in operation and are used to specify weight limitations and restrictions.

On vehicles designed for the North American market, the GVWR can be found alongside other vehicle technical specifications on the Vehicle ID Plate that is usually located on the interior of the B-pillar according to U.S. or Canadian Federal Motor Vehicle Safety Standards (FMVSS). (inside driver door near door latch).




The gross axle weight rating (GAWR) is the maximum distributed weight that may be supported by an axle of a road vehicle. Typically, GAWR is followed by either the letters FR or RR, which indicate front or rear axles respectively.

You can weigh your RV per axle to find out if an axel is overloaded or not. Before you do that fill up all tanks.


Curb weight describes a vehicle which is “parked at the curb” and excludes the weight of any occupants or cargo.
Dry weight further excludes the weight of all consumables, such as fuel and oils.
