Pulling I have gotten as poor as 5.5 mpg. That was pulling an 18000 lb trailer bucking a pretty good wind. I have seen 8.5 mpg pulling a 14000 lb RV no wind. Empty and driving a steady 60-70 mph all highway I have seen 17.5 mpg. I have 20" wheels and the 3:55 gears. I expected better.

I had an 07.5 Dodge with the 6.7 Cummins in it. It was totally stock, 3:55 gears and was lighter than the Ford. The best it could ever do empty on the hwy was about that same 17.5 to 18.5. I think the days of getting 20 mpg on a 7500 lb CCSWB 4x4 truck are over. With the fuel used for regens and all of the other emissions stuff I just don't know if it is doable anymore

If I drive 55-60 which I never do, I can get 20mpg. Pulling my 10k work trailer I get 9-12mpg depending on how I drive it. Unloaded average is 15mpg and thats mixed. 16 to 17 normal highway driving.

I average 16-18 empty. I pull my travel trailer and get 11-12 thats 7000lbs. When I'm plowing snow and in 4 wheel drive 8-9. I was hoping for a little better, but you cant beat the power.

I average 18-19.5 at about 8000-9000' in Colorado mtns. About 12mpg towing a horse trailer. I have about 11K on my F350CC.

It seems that us guys at higher altitudes are getting better mpg's.

The thin air is easier to go through.

Rural driving I am getting 17 to 18. I have not been on an extended highway trip yet but I have every indication that I will get 20. Hauling the boat (~5K lb) I should be able to get 13 to 14 MPG. I am pretty happy with it. Better than my 6.0L
