Very nicely done! Thanks for sharing. I just finished creating box for my spare gas can (plus other stuff) also.
Here's the photos. This is a swing-out bumper; meaning the top part of it swing out away from the camper door. The idea is that I can put spare gas can inside this box and lock it via the hinged top. It is also desgned to be just the right size to fit two sets of snow shoes. I bought a stock Smittybuilt bumper which had swing out tire carrier. I cut off the carrier and welded together this box and welded it to the bumper bar. The bumper was no designed to fit my truck so I built my own attachment brackets and welded it on so that it sits out beyond the back of the camper. Before the camper acted as a bumper because it was longer than the truck (not good). The license plater has a light and there red light in the center is for turns/brakes.
The other picture is something difficult to see. It is a 4 ft long basket (~ 1 ft deep) that is behind the bumper. It will get wet. I can use it to store things like shovel, leveling blocks, etc.
