Keep an eye on Lemons Auctioneers ( https://www.lemonsauctioneers.com/displ ... gories=400
). That's where I got my skoolie for $500 with a bunch of extra goodies. Since they're here in Texas (and most auctions are close to me) I can check the bus(es) you're interested in bidding on. I'm a former trucker, fomer ASE certified mechanic, and I've been doing government surplus for over 12 years. My bus has A/C and a bunch of other goodies (such as new brakes, tires, full tank of fresh fuel, and so on) for free! PM me if you're interested. I know it would be a flight down here, but these busses are good and clean of rust (especially north and west of San Antonio).
Right now there aren't many, but there should be as the summer vacation wraps up.
