i've considered buying an extra bus or 2 per year from the local school district, gutting it, painting it and seeing if i can make a little profit selling it on ebay. I've yet to act on this idea, but i have considered it.
I don't think there is much money in selling buses converted to RV's as the amount of time required to create the masterpiece is worth far more than people are willing to pay.
however, If i got a bus for $1,000 and put $100 worth of paint on it, plus the $50 i'd get paid from the scrap yard for all the seats it seems likely i could sell it for nearly double what i paid for it. If the weather cooperated i think i could do the entire project in a week.
Perhaps i'll try it this spring. I would immagine that a 92 or newer bus with an international dt360 or 466 and auto trans would go for more than 1K on ebay. I think it would be pretty difficult to loose money on the project.
