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.

Hi knoddy,, Last time I checked, 7.5 to 8 here. E450 2017 Sunseeker 32ft, 19,300lb combined weight rolling down the road loaded, pulling Toad 65mph in rolling hills. Congrats on the new rig!

Fuel mileage ford v 10. My 2005 Lexington 26' gets almost every time out 11.5 mpg. There are many factors which affect fuel burn, the box over the cab on class c's is a big factor, along with speed , wind altitude and hills etc. my experience has been 62 mph is the best speed for combining rpm, time to get there traffic etc. last summer's 2000 mile to Yellowstone Salt Lake City and back to Ca. By the way travel at 4 to 5 thousand feet altitude, with a good tail wind on this trip, 15 mpg. Your aerodynamics, weight speed, and elevation will bring the mileage down, but much below 9 seems excessive. Lexidriver.

Boy, you must be doing something right!!! At 62 mph I couldn't get my Lexi to give 11.5 mpg, going downhill with a 40 mph wind blowing behind me. And that's running totally empty. Best my ScanGuage ever showed me was around 8.5, running on flat interstate at 65 mph, without my toad. Loaded for a trip, with my toad, anywhere between 6.5 and 8 mpg, is average.
Are you getting your figures from the gallons to miles or from a Scanguage?

He has a 2016 ford, it will give gallons used on the dash. If his is like mine, it's pretty close to hand calculations.

I'm sure the Lexi aero makes a big difference, not to mention its size and weight. There are pros and cons to every model.

Are you running the 450 or 350 ?? If it is a 350 it has a different diff so that sounds right

I'm averaging just under 8MPG running 65-70 in my 27' Forester. 6.5 MPG when pulling my Mini Cooper toad.
I'm a geek so track mileage with every tank and use the UltraGauge.
