I wouldn't do anything until mid-June or July. Right now the stations have winter blend fuel, oxygenated, and mileage has taken a beating. I went from nearly 19.2 mpg higway to 13.4 mpg with just the fuel change, no other change to my truck. If you mileage doesn't come back with the summer fuel then look at doing something. This is all of course assuming you didn't mod your truck in some way; larger tires, removed a bed cover, leveled, etc.
