Jake Von Slatt bought an old school bus for $2K and turned it into the RV of his dreams. (It reminds me of an old railroad car, when railroad cars used to be posh.) Mr. Von Slatt did most of the re-fabrication himself. He used Craig's List and Freecycle to find materials to recycle into his build. Visit Eco Joe's to watch a video of Mr. Von Slatt giving a tour of his RV bus. To see the bus's conversion, visit Mr. Von Slatt's website. It's really interesting.
