I spent a lot of time collecting pictures of buses and campers. I have over 3000 pics in my motorhome picture file. Here are two pics of strange buses. I will go through and find some more.
This is Casa Azul, a remote electronic surveillance 4x4 truck for one of the many United States Governments spy agency's. Yes that is a 1951 Studebaker welded to the roof, you can see more here http://www.overlandhardware.com/ca-specs.html
