I appreciate the kind words.
The brainstorming sketch is here:

But what I really intended, was made a horizontal cover to hide the gap as seem from directly above. The space between the back of the bed, and the inner edge of the bumper.
I may put a 3-gallon air tank over the frame rails at the front of the bed, but the driveshaft is too high aired out to fit a big tank, and I'll have 4" exhaust from the turbo coming out the passenger side.
Alternatively, I may tuck two 3-gallon tanks inside the rear stepside fenders. I mean, that space isn't being used for anything as it is.
