equal or exceed GVWR. Once the trailer is sold its hitch weight becomes the sole responsibility or its owner.
The vehicle manufacturer can set the GAWR on axles to a value they deem appropriate for that trailer. If there is excess GAWR it just becomes a reserve value. It's true value is what the vehicle manufacturer says it is.
A trailer's GVWR will always remain the same unless the vehicle manufacturer or a certified vehicle modifier changes it.
If a trailer leaves the factory with a functional propene system the full propane tanks become part of the trailers GVW.
