Nice truck, looks a lot cleaner than my 97. Auto or Stick and what gears does it have. Mine is a 5spd with 4.10 gears and my mileage went up with bigger tires because the truck is turning lower RPMs, I'm on 37's now. You probably have 3.55's which are great with 285's, 305's and even 315's. I have a custom fuel plate, 4 inch exhaust, South Bend clutch and a couple gauges. The truck runs well, pulls awesome and still gets 17mpg on the highway if I drive below 70. A few basic and relatively cheap engine mods go a long way. Definitely take care of that KDP too.
