I have 4.10s in my F350 dually. With with a load of 22,500# I get 10 MPG. I drive in a lot of mountains on the west coast. I have also traveled cross country with it and get 10 MPG. I do not know what it gets unloaded as I never drive it that way. The 6.7 will get better mileage than my 6.0 diesel.
