All RV trailers are built to minimum safety standards outlined in various NHTSA regulations and safety standards and in the FMVSS.
Once the trailer is built the manufacturer must
certify the following items; GVWR, GAWR, tire and rim sizes appropriate for each GAWR, recommended cold inflation pressures for those tires, cargo capacity, and, establish a hitch/pin weight for publication in brochures and the vehicle owner manual. That's why - earlier post - I asked the OP to check his certification label. Sometimes manufacturer specs shown in their on-line PDF files don't match-up with the certificating label on the actual trailer.
The hitch/pin weight can be a range or specific figure. If a range the lowest value must be used. If a specific figure, it must be used. When added to the trailer’s total GAWR the sum must
equal or exceed the trailer’s GVWR. After first sale the vehicle owner is totally responsible for hitch/pin weights.
If the maximum load capacity of the certified tires fitted to a trailer axle do not equal or exceed the axle’s established GAWR they are in violation of the minimum FMVSS. Trailer manufacturers are subject to severe monetary penalties and recall action for such fitments.
