i get 10 mpg with the ford f350 6.2 towing livestock. i lock it out of 6thYep!! Truth spoken here. When we drive to OK in this truck not towing we usually stop four times for fuel and put in an average of about 20 gallons each time. I never try to get it down near the 1/4 tank mark on my trips. I already know I'm going to be in the 6-8 MPG range towing with this Hemi powered Ram. Still worth the cost savings and effort to do the move ourselves.
