Sorry for the grainy cell phone photos. The little black box on the top of the console is a control unit for a pair of amber LED's I added to the rear window. Having to drive the ALCAN during my transfer to Alaska, and knowing the winters up here, I wanted some extra warning power out the back in case of whiteout conditions. They easily went into one of my extra fuse slots, but thankfully I only needed them once when I slid off an icy road up in Kodiak.
Overall, I'm still really happy with my choice to build it myself instead of a much bigger console. Haven't had a need to change any of it since I installed it 3 years ago, other than adding the amber lights. My GPS and dash camera run off the 12V outlet, but the dash cam will be hard wired to the retained accy power shortly now that I know about it. The setup worked really well during my massive 5200 mile road trip from New Orleans to Kodiak, AK right after it was installed. Doesn't take up too much room, I can read/hear the radios, and other than my wife turning them down when locals get chatty on GMRS, I haven't had any complaints from her on it.
If you're thinking of doing something similar yourself, I did learn a few lessons.
First off, make sure you have room for wires and connectors, not just physical radio sizes. I got lucky with my planning, but it was tight. I wanted to make this as small as physically possible, and I succeeded, but there isn't much room for tinkering, upgrading, or anything else for that matter.
Second, when working with the sheet metal, wear gloves, and file/grind all your edges. This thing was sharp until I knocked down the edges post-install.
Third, aside from welding my frame, this could really be accomplished by virtually anyone with basic tools. And you could easily solve that with a tube of JB Weld, or come up with a bolt-fit structure design that doesn't need welding. Plan it out, double check fits constantly, and take your time. The most complicated part is planning out how you'll accomplish all of your goals and fit everything with the minimal amount of wasted space.
My finished product may not be as "clean" as a commercially available product, but it is ideally suited to my individual needs. I was able to minimize the loss of useable cab space, kept all my stock dash features (mini-dashbox, 12V outlet, and 110V inverter plug), and fit both radios. Hoping my next project will be finishing the rewiring of my CJ5 so I can wire in my intercom and radios, but first I have to get back to the lower 48 and get the Jeep back from storage (later this summer maybe?).
