A few years ago I was the lead on getting a replacement vehicle for the Region's Solo trailer (nobody wanted to pull it). We ended up with a retirement village bus that we picked up at a local auction for $2500 - 454 motor, big side door with no lift. Gutted it out. I looked at a lot of buses up to that point and I none of them had trailer hitches. We got lucky and made a deal with a local outfit that only charged up $500 to weld up a hitch and reinforced frame rails on the back.
