Purchasing Warped Roof 1997 Bigfoot 2500 9’6”?

You mention hurricanes means your south like me. I'm in central Florida and you could hit a RV dealership or a mobile repair guy with a golf ball hit in any direction. Have someone come and look at it. A couple hundred bucks at most. It doesn't look like water damage to me it looks like the camper is tipped to the rear. The window stuff is nothing to worry about as you can find them on amazon and eBay. Good luck sir!
