FORD F-350 6.2 L V8 Gas. Mileage will go up until the truck is sold. With an aftermarket flat bed. The gas tank is not included in the sale. This is a work truck so it is not in perfect condition. You can see the large dent on the passenger side door. Come check it out and take it for a test drive. Good if you need a solid work truck that runs and gets down the road. Located in Jackson, Wyoming.
