I'm not here to rain on your parade. Follow your dream. That way you will own any mistakes made along the way. I can think of a lot more why-nots than I can whys.
The MOST successful camper-on-trailer forum can be found on the Expedition Portal. The trailer guys on there are THE most inventive of all the thinking-outside-the-box boys.
When I was writing for Off-road.com, I was constantly asked about the efficacy of simply converting an old Chevy 1-ton pickup from two wheel drive to four wheel drive. What could possibly go wrong? Just throw a live front axle on there; a driveshaft; an NP205 transfer case that will fit your transmission and you are good to go. No? No. The fact is, unless you are a very aggressive do-it-yourself-type, and have the chops to pull it off, it's always better to buy a factory version of what you are trying to get to. Good luck with your project. No one on here is wishing you ill. We are just reporting our own bias and experience.
