Jason, I have RV factory envy!! Nice work! Sure wish I had something like that, but my bride wouldn't let me take up some of the 150 x 45 foot backyard for a 2nd garage...
I'm sure you've seen this site, but it has to be one of the better documented build sites that I have seen. http://www.rv7factory.com/index.php
Brad's site is awesome!
Good luck with your build and your site!
