But those numbers are from the dash computer, which has been slightly optimistic when checked against fill-ups. Partly due to the Onan's gas not being measured, I'm sure. "
Jim & I have nearly identical Tigers, except mine weighs less (no generator, no roof A/C) and mine has less wind resistance (no roof A/C, no roof railing). I've used the dash computer mpg reading, the dash computer gallons used/miles driven readings, and my written log book. All come out pretty close to the same.
It's also worth noting that our Tigers are 4WD, which usually get worse mileage than 2WD.
13.8 sounds good. Maybe I should try driving 55-60. Or not. Might get run over at that speed on CA freeways.

That's great. But which one did you reported? 11.54mpg, US or Imperial?

Over the last 4000 miles, my 1994 22.5 ft Chevy class C with the 350 fuel injected engine has averaged 10.75 mpg.

Yes. But yours is a 2006. This is a 1990.
Well, that might actually help. A EFI engine from that time would have very little emmisions control, wich normally would take power away. In same cases, and older engine would do better.

I can understand the low 8.8. The high 17.8 seems like a human error ;-).
Anyway, 12.1 average is great. No human error, I distinctly remember that segment. According to my log book, it happened on October 10, 2003. We were being pushed by about a 40-50 mph wind and we were going down in elevation from the mile high city to 1,080 feet above sea level.
