I get between 11-13 mpg while towing and recently took a 600 mile trip with just the truck and it averaged 18 mpg for the trip.

My 2016 F350, dually, diesel, crew cab, long bed has 4:30 gears. I consider that a plus. With those gears and the Tow/Haul mode, I can move a mountain.
Fuel economy is taken care of by the multi-geared transmission. Depending on terrain, I get 10-12 mpg towing (Tow/Haul mode, cruise control at 59 mph) and I have gotten as high as 21 mpg non-towing 65 mph+.
