(We were all newbies at some point, right?)
As far as pitfalls, problems to avoid -- well there are as many as you can imagine. My suggestion is to read the vast archive of messages here and at the Yahoo groups as well (accessible from the front page of http://www.skoolie.net
I believe). The Search function is your friend.
Also look at the conversion websites -- I think you'll get an idea of the hows and whys of things.
My only suggestion at this point is to make sure there aren't problems lurking under the surface that will become a nightmare later -- extensive rust under the flooring, leaks in the roof, leaky/drafty windows, etc. Better to tackle them now than in a storm in the boondocks, IMO.
Oh my other suggestion is to keep all of us up to date on your conversion, ask lots of questions, and post photos in the gallery!
