Im with some of the other guys if your serious bout hauling stuff on a regular basis do add a leaf. just be warned the rear end will ride rougher unloaded. body lift wudnt be to badd if you painted the chassis to match the black lower half of your truck but rusted frame rail and no gap gaurds looks awful.

^Agreed I prepped and undercoated my frame after I did the body lift which I think everyone with a gmt regardless of a bodylift should do, but have yet to make some gap gaurds but you can really only see the gap directly from the side so I'll eventually get to it.
