There is a guy in tulsa, Ok that only deals with vans. I have gone there regurly and seen many diesels in conversion vans. I almost bought a van that was a fully loaded and converted and even had 4x4. He said no one wanted it and only asked $1000 cause he picked it up for nothing at the auction. I was going to some aeronotics school at the time and was completly broke!!!. Could not afford anything or esle I would have bought that thing. He did have it running saying it ran out of fuel at the auction cause the fuel guage was inaccurate causing the low sell value. It ran great. I don't know if it had a turbo, I never thought to look. But yes, there are many out there, just got to find them and they are usually very cheap.
