Welcome, Clutchski. If you wanted a truck with better mileage than the rest (in real life, regardless of specs), you made the best choice. However, many customisations will reduce mileage. Whether it's a lift kit, non-OEM tires, bull bar... anything that affects aerodynamics or rolling resistance have an effect, mostly for the worse. About the only addition that will make an improvement is a tonneau cover, and that's only for highway mileage.
Of course, the best way to get good mileage is simply to never be in a rush. It's shocking how much of a difference it makes. I'm talking about a 20-30% difference in city and mixed driving. When it comes to highway driving, expect to pay a penalty of about 1% fuel consumption for every 1% faster you go above 60 MPH.
What other kind of plans do you have for your truck?
