The brochure lists my Surveyor as 4139 lbs. The interior luxury package lists 208 lbs., and the exterior luxury package is 267 lbs. That adds up to 4614 lbs……exactly the number on the certificate of origin, and the label in the cabinets. But the trailer was also shipped with (weights are from the brochure): Outside grill (15 lbs.), raised panel fridge doors inserts (18 lbs.), roof ladder (15 lbs.), which is another 48 lbs. that is not reflected with the UVW. After adding propane to the tanks, a battery, and the Reese Dual Cam equipment on the tongue, our Surveyor weighed 4760 lbs. coming across the local quarry scales on the way back from the dealer.
So maybe you can see how the UVW could not be exactly accurate. And then you start adding gear.
As others have posted, the best way to determine the actual UVW is to go across some scales. Weigh the combination, come home and drop the trailer, then head back to the scales and get a weight on your TV. The difference will be your trailer weight.
Rock quarries, grain stores, or CAT scales can help you with that.
You might be just fine with the combo you have, but you need to know those weights, especially if you are close to the limits.
I think the lady at the local rock quarry is getting tired of seeing me.
