I had an 83 Dodge single wheel 1t cargo van. It had a 360 with a 2bbl carb and a magnum cam. I got 17 mpg frequently. Driving the speed limit.
I also put 33" tires on it.
I would guess that with the extra frontage on a class C, 2 more wheels and more weight you'll be lucky to get 12.
990SMT, 640A, TXC450, TE510, ATC350X, ATC200ES, 550MXC, BW200. Need more space in garage.
