I'm pretty much grasping at straws here I loaned the truck to my buddy for about a year, and when I got it back I fixes the egr tube (it was broken), the dpfe sensor, and put manual steering box in (pump was shot), and got an alignment. Everything that he broke is now fixed and its still not getting the mpg it did a year ago.

Cleaning carbon out of your combustion chamber is a good thing to do.
That carbon can make your piston rings stick, adversely effecting compression, increasing blow-by and decreasing available power.
I haven't used Seafoam, but ran a home made water injection system for a few weeks on a previous car to clean out the carbon.
I did see better fuel consumption after it.
