Our '02 (a 32-ft Class A with the EFI Ford V-10) averaged about 7.7 mpg. We didn't tow anything. The good part was that the MPG was altitude independent, We did not like our old 26' Class C whose gas mileage varied between 7 mpg at sea level, but dropped to around 4.5 at about 2500 ft ASL. It had a carb-equipped Ford 460 V-8.
