So I realize this isnt the best condition camper ever but looked interesting at least. Supposedly everything works but the interior could use some new cloth on the seats and bed etc. The guy selling it says it was the neighbors sons. He moved out of the country and asked him to hold it in his yard and sell it for him. This guy doesnt care what it goes for just wants it gone so he listed it for $400. I may be able to buy it for less. What are some major problems to look for?
