Keep the length limit in mind.
One thing that I have been considering is the length of the bus that I want to buy. The major consideration there, with regard to towing, is that there is an overall limit of 53 feet for the rig (please correct me, someone, if I am misstating this.)
A 37 foot bus + a 13 foot Jeep + say, 3 feet of towbar comes in right at 53 feet. Any longer a vehicle or any longer a towbar or any longer a bus and I'm over the limit. Additionally, I want to be able to to (not at the same time) a trailer/workshop, and I have to keep that in mind.
I'm hoping to find a 35 foot bus that has roughly 27 or 28 feet of usable (behind driver's seat) space. I'm reckoning that this would be a 72 passenger bus.
Oh yeah, it also needs to have a DT466 engine, 5/2 speed tranny, 4.5ish rear end, new tires, and air brakes.
And in needs to be priced at $3,000 or less.
If it came with twin 18 year old nymphomaniacs who had just inherited a fortune in liquor company stock, that would be a plus, but I'll settle something close to the mechanical specs.
