Just purchased my first RV! Tell me what you think.

Well that RV was made the year my oldest child was born! I still think of her as a youngster though. Amazing that you have found it in good shape. Good for the former owners. It is a bit hard to spot rot if you are a newbie, but you can just be sure it is buttoned up with caulk and eternabond and prevent any from happening on your watch. In the meantime, can't think of a more fun hobby! Congratulations!
