We have a 45 foot Monaco Signature with a 600 hp Cummins and we average anywhere from 5 to 6 mpg. Our last rig was a 2002 HR Endeavor with a 330 Cummins and we averaged 8 to 9 mpg, which was about what we got when we towed a 27 foot fifth wheel with a 2000 Toyota Tundra. Many years ago a fellow RVer in Louisiana told me that if anyone ever tells you they get good fuel mileage with an RV they're lying through their teeth. I think he hit the nail on the head. After all, does anyone go shopping for an RV with fuel economy being a high priority? If so, they should stick to camping in a tent.
