Not meaning to insult anyone, but I can't value statements of "Getting X amount of mpg at 55mph". I could say our rig gets 13-14mpg at 55 mph (per our ScanGauge-II), but our reality is that our "trip" average is around 9.5 mpg when we bring along our 2006 Jeep Liberty, and around 10.5 mpg when leaving it home. Calculation is based on fuel purchased & miles driven, averaged over the duration of the trip. Not the SG-II. We do live near Chicago so much of our driving is across the great plains under so-called "ideal" mpg conditions. Our B+ E350 rig weighs around 10,000 pounds on trips and is more aerodynamic than most class Cs. I could easily reduce the average with a lead foot, and could increase it by slowing down to 55 mph. I generally cruise 5mph over the posted speed limit for towing when applicable, but never over 70 mph.

We do have an on-board 4000 Onan generator which negatively impacts our numbers, so my stated average mpg is conservative.

Howdy Ron. I understand your escepticismo. We were surprised as well. But we check our numbers using both the old fashioned method and comparing to the scan gauge and yah we can achieve 12 plus routinely. Very diplomatically written by the way. :).

Happy and safe trails. :)

Have just completed driving our 23 ft Coach House about 1500 miles in WA, ID, and MT; averaged a little over 10 mpg, sometimes 11 sometimes 10. Didn't use cruise control unless on very flat terrain (avoid shifting going up slight hills) and driving about 60 mph, sometimes 55+ and sometimes 65+. It's on the E450 chassis and well streamlined.

I have a fleetwood tioga 25g it is 26 feet

it is the e450....4.56 rear end v10 8.5 mpg at 55 mph

"if" you get an e350 you get a 4.10 rear end and a v8 (5.4) you might get better mileage.

as long as that engine stays together I will live with the fuel mileage.

The E350 with the 4.10 gears in a smaller C with the lower air resistance of a B plus front end will easily achieve 12 or better if you keep it around 55 mph. If not in hilly country we have acheived 14 on some trips.

when we first got the rv we got about 8 but mainly in the mountains. On our trip last summer it was 8 in places 9 in some but generally around 8.5 towing a hyundai elantra about 2800 lbs. Best we got was almost 10 crossing nebraska drove 70 mph most of the way also into colorado. It was no better at 65 and no worse at 70 and wife hates to go slow and I dont blame her. we drive our PSD f350 at 80 when we travel with it and get decent milage. But ours is a B+ so we dont have the big sail over the cab and that could be the difference. I do run a 5 star tuner also.

Got about 9.3 mpg on the way back from Maine last Sunday. No toad. I think that is the best I have ever got. Otherwise 7.5 to 8 mpg. It is what it is!

What is the weight?

I have a 2000 V10 E450 23' and tow a CRV on a dolly.
It has 41,000 miles on it.
I stay around 60 MPH and usually get 8.5 MPG.

Speed up if you want fewer MPG.

About 7, driving 62 and about 18000# with the toad. Touring and camping are wonderful in the RV. If time/distance are important we drive a car or buy plane tickets.

Well, our V10 does beat SOMETHING on fuel mileage: My daughter's horse gets far worse distance-unit per fuel-unit when standing around in our back yard than my V10 does when parked around in our back yard. The horse is way more expensive in this mode ... WAY, WAY less horsepower, too.
