There's a whole lot of rack goin' on here! Seems overpowering for a smaller truck, but is for specific uses that make sense for this business. Notice the taller sides, stop in front of rack but not all the way forward. Notice that it is designed to have cargo on both sides yet leave the center area accessible to the cargo area. Notice also the forward structural support posts. Notice the double supports where attached to the body and also notice the width of the rack assembly for maximum space available. Of course, the whole thing is bolted and thereby removable just in case they need some major engine work where the cab is removed on the Ford this package rests on. Last, notice the spare tire mounted in the bed area.
