Within the last few years durability and quality control are a complete disaster. Go and inspect before even thinking of buying and bring along a couple extra set of eyes. Everything shiny and new can cloud a buyers vision that will most likely bite you in the cheeks down the road. Everything from non connected receptacles, loose water fittings, wood chips in the fresh water tank and water heater and piping, lack of caulking in the shower, missing or improperly caulked windows. Windows not installed level inn the openings, screws stripped holding window frames together, etc, etc. It's a real poop show. Bring an ladder and make sure to check the roof and all seals too. Fore warned is fore armed.
