Hi,

If I drive 48 mph I get 9.05 miles per gallon US.

If I had a 3.73 rear end instead of the 4.12 I might do a little bit better.

I'm adding air tabs in about three weeks and will be posting the results on rvnet.

Our shorter/lighter aerodynamic rig as seen in my signature, completely empty and no tow would average between 11-12 mpg if I limited my top speed to 55 mph.

Loaded up, the way we drive, the places we go, here is what we get.
4000 & 5000 mile trip averages while towing 100% of the time, we get 9.2 mpg
Once only, loaded with people, 800 mile trip but NO tow, we averaged 10.2 mpg

I wonder if your friend is using a Scangauge in determining his mpg. I suppose I too may see 15 mpg at times under ideal conditions. But that is not a realistic method for determining mpg.

the scangauge will also show an average mpg. mine shows around 9.8 to 10 on my monthly trip to work and back. 55 miles round trip, flat except for overpasses, a few lights on each end of the trip, around 60 mph. unloaded except for me and fuel. and the junk we never remove.

The Ford V-10 is great engine but contrary to popular belief the "10" does not refer to the number of cylinders. It is the mileage that you will never, ever, no how, no way, see regardless of what you are driving/pulling.


ROFL!!!

We DID see 10 ONCE on our 28' V-10; I attribute that to an extended construction zone that kept us at 50-55 mph.

Ours, with its "square" shoulders and tall roof line (in other words - not particularly aerodynamic), consistently gets 8.5 mpg at 63 mph (or 8 pulling a toad). I can see where a shorter and more rounded profile *might* get 10+, if driven slowly??

I can get 10 mpg in a 31' if loaded light, not towing and no more than 55mph. But, I figure about 8 for planning purposes as that is a more realistic average.....But 15? Only coasting down the mountains

I hope I can get 10 to 12 mpg with my old 1979 Dodge 21 footer with a 3 speed auto and a 440cid engine, I have never owned a V10 but I would think that 10 to 11.5 MPG would be the best ever.

A friend told me that they are getting 13-18 mpg with a V10 Ford engine in a 29 ft class c.

That is the mileage that one will get with a 19' Class B on a Ford E350 with the 5.4 V8 engine. I've got 3 years of fill-ups to back my numbers up.

With a V-10... 29' Class C? Not a chance...
