DC RW package with 285/75/17 Nitto Terra grapplers, my wife, two daughters, two small dogs and my fat azz from our house to Pagosa Springs & back including a trip into town for shopping yielded over 17 mpg. Not sure exactly how much as I haven't fueled up yet, but just over half a tank for 240+ miles is damn good for a full size truck running 65 up and down mountains.

Tires have a lot to do with fuel mileage.
The biggest killer of mileage is friction.
Friction caused by the larger foot print of bigger and wider tires.
If you have 2 identicle tires and the only difference is width, the wider one will give you poorer fuel mileage.
You have greater friction due not only the increased contact patch on the pavement but also increased wind resistance while driving down the road due to the wider tire.
Pretty simple physics really.
You want better mileage put skinny little tires on your truck.

You nailed it. (the original) Mr. Creosote was from England and weighed himself in stones.
When I moved here and applied for a driving license I told the woman at DMV my weight in stones, she said "like what!"

About a thousand different things figure into mileage. Just off the top of my head: Weather, gas formulation, the truck's body-style, driving style, traffic pattern, wheel and tire size and weight, how much junk you carry in the truck. Unless you can say every single variable in your situation is exactly the same as every single variable in the next person's situation, you may not get the same mileage. If you don't have much stop and go with these trucks high teens is very attainable. If you are always stopping and going expect to see 11-13 mpg.
