real world fuel mileage

8.2 MPG over the past 30,000 miles. Individual fill-up mileages ranged from just under 5 MPG to just over 12 MPG, depending on driving conditions: mostly cruise speed, headwinds and tailwinds, and for a couple of trips, grades.

There are lots of real worlds. 24' E450 Class C 9.2 MPG overall. Range 7.8 to 11 MPG.

We get 8 to 10 MPG depending on wind and terrain. I drive by the tachometer, and 2100 to 2200 RPM (about 58 to 60 MPH) gives us the best mileage.

Anything much over 60 MPH, and the mileage goes down dramatically. It took me years to realize it, but it's all about being safe and enjoying the journey, rather than getting somewhere fast.

Real world fuel mileage ??? There are just so many variables. It all depends on the size of the unit, where and how it is driven, and how the mpg is calculated. I know with my previous 24' Class C, over 4 years of trips, I averaged 10.3 mpg. I saw anywhere from 7-12 mpg on trips. All these mpg figures are from my scan gauge, since I never hand calculated mpg.
My 31K has been between 7 and 9.5ish. The average might be a little over 8. Haven't bothered to figure it out.

Detailed Hand-Calculated Trip Average (5000 mile round-trip journey) is quite consistent from one year/trip to the next.

All stock 2007 E350 chassis with 6.8L-V10 engine and Torqshift transmission.
- 9.5 mpg towing the Jeep Liberty pictured
- 10.5 mpg not towing anything


I think we could improve fuel economy a little if we were not trying to make better time across the great plains.

Also the generator steals fuel which is negatively but marginally influential as we don't run it that much.

30 ft class c V-10. MPG ranges 7 to 11 with toad. Depends lot's on wind and terrain.

At 55, about 7 to 8 mpg.
At 62, about 8 to 9 mpg.
at 72, about 6 mpg.

I have averaged 9 mpg over the past few years towing my Subaru and running the genny occasionally.

Chevy 6.0L, about 12000 lbs.

We just did this on another thread over the last week and the average for a class C all sizes was 8.3mpg and that was at a 60mph speed and towing a toad or not. Drive fast get less..... drive slower did not matter.

I drive a 2000 Winnebago Minnie Winnie V-10 and get from 8-11 MPG depending on conditions such as into the wind, flat land, hills, etc. I pull a 2008 Nissan Versa and don't notice much difference in MPG. When it's hot I also run the generator and A/C and there might be a little difference. Nothing to speak of. When everything works, what a way to travel. I'm not going to worry about pennies.

see where u had it for sale jan 13, have never heard of a 30 ' c getting 11, wish mine could what is your weight? also what is your ccc
