M109s can be a lot of work but I have enjoyed mine and think you will like it as a base for a camper too. They have a tendency to get rust on the roof and develop water leaks, so check for that and correct as necessary before spending much effort on it. If water does get in, there is a steel floor pan under the oak flooring that rusts out, so be prepared to replace it too. Good luck! I have a build thread on here that shows what I did, and feel free to PM me if you have something specific you need help with.
