From the website VonSlatt:
In January of 2005 I took delivery of a 1989 Thomas Saf-T-Liner, a flat-nosed diesel school bus with about 100,000 miles on it that I bought on eBay for $2000. Over the next 18 months I converted this old school bus into a family camper. Wherever possible re-used and recycled material were used, mostly acquired from our town dump, Craigslist and friend's demolition projects. All stages of this project are documented on these page
If converting a school bus to a rv is too much of a hassle, why not try a motorhome rental from Motorhome Roadtrip?
