If I was doing another bus I'd do a 30 foot dog-nose, they can get into almost any campground. I saw several that went to auction a year and a half ago, with a dt360 and mt643. They went for about $2400, and were in excellent condition. In my state, the state government has slashed money for the districts to buy new buses, and the supply of good buses is drying up.
This is the kinda bus they auction now: http://www.publicsurplus.com/sms/state, ... auc=652438
An OBTW: the damage doesn't look all that bad, just sheet metal. YMMV.
