What GVWR Means on a Trailer

GVWR stands for Gross Vehicle Weight Rating. On a trailer it is the maximum the trailer is allowed to weigh in total: the empty trailer plus everything loaded onto it. It is not the payload and it is not the empty weight. If a trailer has a 14,000 lb GVWR and weighs 3,500 lb empty, the most you can legally and safely put on it is 10,500 lb.

GVWR is a ceiling, not a capacity

The number stamped on the rating plate is the total the manufacturer certified the frame, axles, tires and brakes to handle. To get your usable payload, subtract the trailer's empty weight from the GVWR. That difference is what you can actually carry.

The related ratings

GAWR is the Gross Axle Weight Rating, the maximum on any single axle. A tandem-axle trailer with two 7,000 lb axles has a 14,000 lb GAWR total, which is normally where its GVWR comes from.

Payload is GVWR minus empty weight.

Tongue weight is carried by the tow vehicle, not the trailer axles, so it counts against your vehicle's payload.

Why exceeding it matters

Three reasons, in order of how quickly they hurt. It voids the manufacturer's warranty, and overloading is the most common cause of a declined claim. It is a citable offense at a weigh station and in an accident investigation. And it is a genuine safety limit, not a conservative suggestion, because axles, tires and brakes are all sized to that number.

How to use it when buying

Work from the heaviest thing you will ever haul, add the weight of the trailer, and buy above that. Do not buy for the average load. A skid steer at 7,800 lb on a trailer that weighs 3,000 lb empty needs at least a 14K GVWR unit, not a 10K.
