I want 25-30 foot bus, I am 6 foot tall so need headroom. Want handicap lift for mobility scooter but ramp could work. Boondocking in western Oregon mostly but want to go over the big pass 2 times a year (4500) foot. Will have 3 dogs so campgrounds do not like me. Shuttle bus might work, sure like the mileage to be better. Have chevy cobalt which can be towed wheels down. Is there one company that makes shorter buses with headroom? I am not mechanical so bus would need to go to shop if it has problems, so need good parts supply. Very confusing to shop for bus without knowing which companies make what I need.
