At 60 MPH my tach is indicating about 2400 rpm which seems to me a little high. I have a f-150 with a 5.4 litre 3 speed with overdrive and get about 2200 rpm at 70 mph. A v-10 with four speed with O.D. should not be taching that hard IMHO. I am going to have Ford check it out.

Our 2011 3170DS with 6000miles is averaging around 8mpg, so I guess a little improvement through break-in period.

Motorhomes have much "steeper" gearing in the rear end compared to an F150. Your F150 probably has 3:55 or 3:73's and motorhomes typically have 4:56's or numerically higher!

So what you are seeing on your tach is typical for that kind of gearing. I say completely normal.

[QUOTE=vacouple;167418]Had a nice camping trip despite storms , wind etc. with our new 2300. All systems worker great.....heat , air, reefer, water heater, elect. Checked gas mileage for the trip and We have the ford V-10 and as far as I can tell driving in the range of 55-60 mph most of the time unless putting along we got a measly 7.5 mpg!!?? I was guessing about 10 with such a small class c but 7??? Now it only has about 1000 miles on it so please tell me that after it is broken in it will get better mileage..anyone with any MPG estimates chime in please.

Here's a good suggestion try looking into installing an electric fan
Assembly. When I did this to lower my trans temps in case
They got high. I in fact raised my mpg since the clutch fan
does not run now. 1 mpg difference over 26 gallons made
a difference enough for the price of the fan.

We have a 2007 Sunseeker 2900 with a Ford E-450 V10 and got 7.8 mpg on our last weekend trip. It was mostly highway driving (55-60 mph) and a few hills and no real wind. I was expecting 8 to 10 mpg, but I purchased it knowing it would not be great on mileage.

WOW way to make me fell better peeps You all have much bigger motor homes and get about the same mileage LOL.....I do appreciate all the input and hope everyone else can chime in too. This way we can kind of bump off ideas together on how to get better mileage or just get ideas about what is normal. Now I gotta go look up rearend numbers ......

I think that you should see a bit of improvement as the 2300 gets broken in and you become more familiar with its optimal operation. Do, however, take note of the fact that from Newport News to the OBX you were operating basically on flat ground and at sea level, which would have given you an advantage to start out with. I also see that you noted that it was windy - the big question is whether it was a headwind or tailwind.
