In the past half year I have been looking for long (36 ft+) mid engine school buses for sale and cannot find any. Based on observation, it seems that none were made in the 1990's and later. Is that true? Crown made some and Gillig made some. My fettish with the mid-engine busses....I would love to put a big jacuzzi in the rear of the bus and still have enough room to have loft storage over it - maybe even a loft bedroom. I don't want front engine because of the space lost to the drive shaft. Also (my own observation) the pre 1990's busses seem to be a little short on head room. I am hoping this will be my tiny home - a 24/7/52 dwelling place, so the underfloor storage is pretty important. Ｉ know that there were a couple of pancake diesel engines made in earlier years, but the one I looked up weighed more than a ton by itself and might have been a 2 stroke engine to boot, so putting a pancake engine in the back is not an option. Has anyone tried to flip their differential and put the rear engine in front of the differential? In theory it is easy - not sure about the $$$ of practice.
