 I have a light foot on the pedal but average only 14.5 mpg with 90% highway driving which is very disappointing considering the 3.5 turbo's claimed mpg of 21. Towing 7000 pounds at 65 mph however gives me 12 mpg: makes no sense. Ride should be stiffer. Seats very comfy. Should have more cabin storage. Incredible leg room in supercrew. Wish I bought an F-250.
