@jscherb I got a sketch from many moons ago similar to what you have above...but I never digitized it.
I want to play with some concepts to make this work for my application. I'm currently running a Titan fuel carrier (the older style - the left side sticks out a bit from the tire) and may end up blocking both lights. I have an ARB steel rear bumper that I picked up for cheap and would use as a base. I also picked up a tire carrier (

The dual swing would be cool from a table/chuck box/work surface perspective, but too annoying on a daily - so I am just going to go with a single swing arm. I don't intend to load much weight into the cargo box, so am not too terribly worried about leverage on the pivot.
