We bought a 303 last spring and so far are very happy with it. The materials and appliances are fairly typical for the price range but the fit and finish on our unit was outstanding. Had a furnace problem that turned out to be debris in the burner, either from installation or manufacture. Dealer fixed it no problem. We haven't used it in severe weather yet. The single AC was OK into the high eighties but I think might struggle much above that. Biggest issue for me was the 15" wheels. I swapped them with the 16's from our old rig which was actually a lighter trailer.
