I get 11-13 mpg with my '15 F250. The bigger factors are wind, terrain, and traffic. Having come from a '13 Sierra 1500, diesel is definitely the way to go. I will never tow with a gas motor again. My trailer is right around 11,500 loaded and my truck tows is easily. Like Ultraboy said, let the torque work for you. On the interstate, I set the cruise at 70 and except for bigger hills, the truck never downshifts. The GMC was always downshifting, even with a 16' trailer that weighed less than half of my current TH. I'm very happy with the truck overall, very happy with the towing.

I know there are people like me who write down every time you get fuel and calculate True MPG, we have a few f450 6.0 (still running if you can believe that!) so I know about the difference between the too. I just need to convince the suits (skirt in my case) with data that 6.7 is the way to go. All I need is f??, trailer weight and mpg (lie-o-meter or true) we run mostly east coast so flat/hilly terrain. Thank you all in advance for your help !
I will provide solid data after my run next week when I pick up my new 2016 Heritage Glen 272RL with my 2014 F250, 6.7L diesel. The run will be 1,150 miles one way.

DH checked our mileage last week - had to go to Cincy to pickup a car for the DS. He pulled a car hauler up there and got 18.3 mpg and got 13.2 with the car hauler full and headed back into the mountains. Ours is a 2015 Superduty F250 6.7 crew cab, but it is not a dually.
