go to the bottom of page where it says F Series Super Duty and click on the arrow. Then scroll up till you see vehicle locator by Ford employees. Put your info there and they will find you truck, they do this on their own time so it might take a few hours, but they are great people.

I have an '08 F250 with the diesel and 3.73 rear end. I get between 15 and 18 mpg on the highway and about 14 in town. You have to keep your foot oout of it to get decent milage.
