Our V-10/F53 Georgetown 32-footer (an '02) got a consistent 7.2 mpg over the 6000 miles we drove it. The good thing was, it didn't change with altitude, thanks to EFI. By comparison, our previous 1985 26' Class C, with a 460 (carburated), got 6.5 at sea level and about 4.5 at 2000 feet. We have a lot of high altitude roads around here - Washington Pass on SR-20 is 5200'.
We didn't tow anything with either rig.
