Rear end overhang height?
I have a 1988 s1853 40ft bus. I'm building it to haul a car in the back. It's been a few years long project waiting to be started, been back and forth on how to do it best, on the back on a flat bed. A rollback type deal or a ramp truck. I think I've decided I want to keep it enclosed as originally planned but getting a car 43" up is not really a feasible setup. I'm thinking I'll have the ramp level off over the rear wheel tubs and angle downward to the rear where it will be hinged at the bottom. I'll cut a pie section from the frame up to the top rail, behind the spring perches, remove all the rivets holding the floor box/c channel sides to the body and bend the entire frame and floor down. it will be reaatached to the sides at the proper height required to keep the structure solid. I'll trim the frame ends to be level with the ground at the desired height and plate and box the entire rear section. Slice the rear body cap off and frame up inside to be the folding door/most of the loading ramp.
I can't find my dimensions at the moment but I believe my back bumper is 30" off the ground. There is a 4" exhaust pipe that's never touched ground below it, so like 25" I think off the top of my head. I'm trying to figure out how low I can reasonably safely go back there without causing myself issues. It's not going to be off road adventuring. Just thinking about the occasional weird parking lot hilly entrance and dragging the tail. It will be super beefy but i will need to be sure I don't ever tweak anything that could cause door opening issues. Looking at an angle from above the rear wheel wells rearward an ideal ramp height at the rear of where the cap ends would be about 22-24“ and the floor is 3“ thick plus a few inches for the frame cap with the massive pivot pins for the door.
So essentially I'm trying to get some feedback on how low anyone has had the rear of thier buss without a big scraper problem, maybe how high your hitch is without issue on a fullsize bus?
If I could get away with 18" it would be awesome for my needed ramp length.
