I am about to buy this truck from Florida and I am wondering what the gas mileage will be like on the highway. I live in Indiana so I am just trying to get a good idea of how much it will cost as I am guessing it will be in upwards of one grand. It has normal stock tires, no mods, and auto trans. If you could also provide the city mpg as well that would be great too. I can't find this info anywhere so please list source(s) or if it is by personal experience. Thanks so much and will reward with points for best answer.
