RV weight terminology
Everyone should have a basic understanding of weight terms. Do your research to avoid becoming a statistic regarding overloaded RVs.
Gross Vehicle Weight Rating (GVWR):
The maximum allowable vehicle weight when fully loaded for travel, including vehicle, cargo, fluids and fuel, passengers, and towed vehicle tongue weight. RVs, towing vehicles, and trailers have GVWRs.
Unloaded Vehicle Weight or Dry Weight (UVW):
The actual weight of the factory built trailer or truck. The UVW does not include passengers, cargo, fresh water, LP gas, or aftermarket accessories.
Load Capacity (CCC):
The maximum allowable weight of personal belongings that can be added. CCC is equal to or less than GVWR minus UVW, total weight of fresh water and total weight of LP gas.
Gross Axle Weight Rating (GAWR):
Each axis has a GAWR. It is the maximum allowable weight that the components (tires, wheels, brakes) of each axle are designed to support.
Gross Combined Weight Rating (GCWR):
The maximum allowable weight of the tow vehicle and trailer combined when both are fully loaded for travel. GCWR also applies to a motorhome that is towing a vehicle or trailer behind it. GCWR minus GVWR represents the allowed weight for the towed vehicle. Note: The tow vehicle mounted hitch receiver should be rated for this amount of weight. If it’s rated for less, that’s the maximum amount it can tow.
Gross Vehicle Weight or Gross Trailer Weight (GVW), (GTW):
This is not a rating; This is the actual weight of the tow vehicle or trailer when fully loaded for travel. This includes the vehicle, cargo, fluids and fuel, passengers, and the tongue weight of the towed vehicle.
Hitch Weight or Tongue Weight (TW):
The amount of weight that presses down on the vehicle hitch or fifth wheel linkage when the trailer is fully loaded for travel.
