back when i was 20 yrs old i bought a 1956 6800 school bus, this was not your fathers school bus
220 inch frame, 48 passenger, carpenter body, 4 speed granny, 2 speed axle (oem) and a 1970 pre-emissions 454 motor
it was partially outfitted for camping when i bought it, i finished it
the living room in back had 2 couches facing each other, that folded out into a super king bed
kitchen had a propane electric fridge, 3 burner stove, 4 seat dinette and 6 foot counter with a sink in it
for a 56 bus it had no problem cruising on the freeway, 80 mph barely broke a sweat
with the 454, hills and mountains were no problem either, low on the 2-speed axle would do 60 uphill
of course it never got better than 7 mpg but it got it in style
this pic was taken in 1980 on our honeymoon, gibb gilchrist ferry is still in service out on galveston island
