Was looking at shipping information on the diamondback website today, and came across their outlet page. I do not know what truck you have on order, the bed length, or your taste in cosmetics (aluminum or flat black) but I saw this on their website used on the outlet page, has some cosmetic damage but discounted with the SXS kit installed. Not sure if it will work but figured I would share.
