Jack, looks great! I really love my flatbed, ill be adding two under body box's in the rear in the next few months. with only a few things i would do different next time. I installed my own as well, and honestly the biggest pain was the fuel filler neck. if i were to do it again, i would do that different. Currently mine is routed above the driver side tool box, this causes the filler hose to be flat the depth of the box prior to dropping, causes slow fill. If that station has a nozzle condom it wont fill at all w/o holding the rubber up,
Looking forward to your box additions.
