Man, your going to have to include more info here! What mileage are you getting, maybe it is normal for the truck you drive. What kind of issues have you had, etc... It could be difficult for people to help you with such limited info.

midnight36, you are already at a disadvantage because you have a truck meeting the new epa requirements. The ends Ford and International have had to go to, to meet these requirements is really hurting the mpg on these trucks. The best advice I can give you, without doing any potential warranty voiding modifications, is to stay on top of the recommended maintenance, keep a light foot, check to see if a reflash is available for your truck (note: some report improved mpg with a reflash, some report a decrease), and maybe look into the larger air dam if you have a Job 1.

Poor design, poor execution and the EPA.
I get 11 in Suburban driving and 14 on the highway at exactly 70mph.

Don't do 70. I don't know about Florida, but in California, the speed limit on a lot of the major highways is 65. If you can drop your speed to between 55 and 62, you'll get 15+ guaranteed.
