Keystone likes to muddy the waters by advertising the trailer’s shipping weight. It’s not an official weight. It’s just for that shipment. To double check their numbers; get the trailer’s published cargo capacity from the cargo label and add it to the shipping weight. If the numbers equal the trailer’s GVWR the shipping weight is a true UVW. It gets muddy when they do not match.

FMVSS states that the vehicle manufacturer will use the vehicle UVW to establish cargo capacity. Shipping weight may be much less than UVW because the vehicle may leave the factory without full propane tanks. Those items are clearly defined in the regulations as part of the trailer’s UVW.

When you find and read the definition for curb weight you will see it’s not applicable with RV trailers. It’s an automotive term where the measured weights differ.
