Please take notice of GoPackGo's speeds he posted.

Between 55 - 60 MPH.

I just traded in my 2011 F 350 dually w/6.7L diesel and 3:73 rear axle.

At those same speeds with that truck, I also could get 20 MPG, but only on those rare occasions here in the northern great plains when the wind was NOT blowing.

Usually in the 18 plus range at those speeds.
