In that range... I have a Coachmen Concord 300DS. Worst tank so far was around 6.1 mpg. That was bucking some pretty strong headwinds and running the generator full time. Best was about 8.75 mpg, that was all 55-60 mph divided four lane with a tailwind. The only thing I worry about with fuel mileage is getting to the fuel stop before I run out!

Tell us more details...are you running on flat, level land at sea level, or pacific mountains, or.....

Are you also running the generator because that uses fuel as well and throws off your mpg calcs.

If your using the old method of dividing the miles traveled by the # of gallons you pumped it is NOT an accurate measure. Things like heat, humidity, a slight incline at the pumps will all have an effect on the # of gallons you put into the tank. Just a difference of 1-2 gallons can throw your calculations out the window.
Only accurate way to keep track of mpg is to get a Scan Guage. It's hooked directly to the OBD port, and gets it's info directly from the computer. It will give you the mpg per tank, and also keep a running average over a period of time/miles. And, it's accurate.
Same guage will also keep track of engine temps, speed (mph). You will find that your speedo is off by as much as 3-5 mph when compared to the Scan Guage.
As for your mileage that you posted...it's actually in the "good" range for a V-10 class c.
As for me, I don't care a whit what my mileage is. We bought the rig to have fun, and experience the USA and what's out there.

Another option is an OBD app for your iPhone along with a wifi adapter for the OBD port. Cost is around $25 total and provides much of the info a scan gauge does for much less.

from Connecticut up through Niagara falls across to MI and up to Mackinaw. So far mostly flat. As for the generator it is on propane so not a factor. As for accuracy a gallon each way is not going to make a big difference. As has been said its for the fun and the sites. I was just interested in comparison with other MH's not a discussion on how to precisely calculate MPG to 6 decimal points

That's the way to look at it, for the fun and the experience.
Some just get so obsessed with mileage, cost, fuel usage, ect, that I wonder how they can be enjoying their rigs. If you have to worry about every 1/10 gallon used, spending a few dollars more or less per trip, how can you have fun.
I sometimes wonder why they even bought an rv.
