Related Glossary Terms

GVWR

Gross Vehicle Weight Rating, or GVWR, is the maximum allowable weight of an RV including cargo, fluids, and passengers. Staying within GVWR is essential for safe handling, braking, and compliance.

GCWR

Gross Combined Weight Rating, or GCWR, is the maximum total allowable weight of a tow vehicle plus the RV or trailer it is pulling. It is one of the most important towing specifications to understand before buying or towing an RV.

Payload Capacity

Payload capacity is the maximum combined weight of cargo, passengers, fluids, and gear that a vehicle or RV can safely carry. It is an important figure for both tow vehicles and RVs.

Dry Weight

Dry weight is the weight of an RV without cargo, fluids, propane, or passengers. It is often used as a starting point when estimating towing requirements.

Tongue Weight

Tongue weight is the downward force a trailer places on the hitch of the tow vehicle. Proper tongue weight is critical for towing stability, steering control, and safety.

Hitch Weight

Hitch weight is the amount of weight a trailer places on the hitch of the tow vehicle. It is closely related to tongue weight and helps determine whether a towing setup is safe.

Curb Weight

Curb weight is the weight of a vehicle with standard equipment and fuel but without passengers or cargo. It is often used when evaluating tow vehicle and payload calculations.

Weight Distribution Hitch

A weight distribution hitch helps spread trailer weight more evenly across the tow vehicle and trailer axles. It improves towing stability, braking, and overall handling.
