2000 Ford E350 27' Four Winds class C.

Overall average for ~10,000 miles is 9.87

But no slouch at passing or climbing mountain passes here abouts.

1999 Ford V-10 (with 83,211 miles on it) under a 30' class A (Itasca) without slides & always pulling a KarKaddy dolly with Vibe. During the 30,088 miles that I have driven it (including quite a few mountains but limited generator usage) total average MPG has been 8.44 @ 60 mph interstate & generally 55 mph otherwise.

pulling 12,600 lbs averages about 7.5-8.5 mpg depending on headwind and pulls like diesel. My e350 van v10 pulling my old 8500 lbs TT or my 9800 lbs Car hauler was about 8.5-9.5 but no where near the power of my 8.1/ally.
