I would do it again in a heart beat. I purchased my '81 Scamp
on Ebay and had it shipped to me in KS from CT, without seeing it. It was a shell on wheels pretty much. It took me 2 months, working night and weekends on it, and it turned out great!
The main thing about re-building your RV is planning. I sat down and drew everything out, and wrote on paper how I was going to do it. It helps a ton! My turned out Perfect in my mind, with a few stupid mistakes here and there, but not to noticeable.
The great thing about the whole thing, is that when your done, you have so much pride in the dumb closet on wheels that you feel like your a part of it, as you can say " I built that with my own two hands".
I spent about $3500 total on mine, with $1200 for shell, $500 Shipping, and then the rest is the cost of the rebuilt materials. I didn't go with the cheapest thing either, so you could problebly cut some corners here and there to get costs down if you wanted to.
I still have one last thing to do.... get the exterior painted. When your done with the interior, you have pretty much butchered the shell with screw holes and so on. It worked out good for me, as I am planning to paint
it to match my car.... I will try to attach a picture to this post!
