Taking a lesson from the Idaho Rob school of making your truck light, take off the tow hitch, spare tire carrier, extra battery, tail gate, back seat front tow hooks and front and rear bumpers. Don't think he ever took of the bumpers but if you want to get into the 10 on street tires I would, hell I even take out the front passanger's seat. Nerf bars too if you have them.
Back seats out, the truck has a roll pan, no spare tire stuff, one battery, no hitches, and tail gates off. I need to weight it and see what it weighs with the roll bar.
