Stock size tires if you are running bigger ones. Tonneau covers are supposed to help. Other than that, keep your foot out of it. I can get up to 15-16 mpg with my dad's truck with 4.10s, which is our work truck and it weighs just over 9k lbs. I keep my foot out of it and keep it under 2k rpms going down the highway.

I've put almost 18k on my truck since January, and 20-21mpg is about what I get driving like an old man on the interstate. Sux being the slowest guy out there, but can go over 600 miles between fill ups with the OE tanks. Drops to 18mpg in local traffic.

I have a manual transmission and run 265/75x16 rubber.

I'm going to go to 3.73 or 3.55 when I redo the axles to see if I can get anything else from it.

I get 18mpg city and 20-22mpg highway w/ 35" tires and a 6" lift. It's all in how you drive it.

Electric fans, might add a little, I am sure it would and plan on doing it soon, run full synthetic oil throughout truck would help a little too i would think about 1-1.5 with both would be fair to say. I can normaly get about 19-20 hwy if im good, with the 35's and still run 3.55's, i think i am going to drop down to 33's next time i get tires and go with a more street friendly tire as i dont take my truck off-road.
