Since the Desert Rendezvous is coming up soon and it will likely be hot, I decided to get motivated and finish mounting the ARB awning I purchased last year. I also want to be be able to put a removable rack on for hauling things like kayaks, and have a place to mount side-facing off-road lights.
As anyone who has one knows, the Flippac is tricky to mount things to. You have to deal with the following:
1. The lid is not considered a great place to mount things to, as it flips over and is not really designed to have penetrations.
2. The sides have a limited number of places suitable for drilling holes. There is a 1.5" square steel tube running the length of the shell. You can access it by drilling 1.0" down from the top of the shell, as measured when opened. On the driver side, the interior lights are mounted to plywood squares that need to be avoided, and on the passenger side, the the Aluminum extrusion for the hammock is riveted to the tube. On the outside, whatever you hang needs to be able to clear the latches used for popping the top. The crank attaches on the driver-side and needs to be able to sweep through 180 degrees unobstructed.
With that in mind, I designed a set of roof mounts out of stainless steel. They mount with two 1/4-20 bolts. On the top, there is an "artificial drip rail" which can hold a roof rack base. The front mounts have a flange for mounting my flood lights, and the awning itself attaches with 2.5" door hinges. I got the inspiration from this thread:

I had a 4" strip of 12GA stainless steel sheared at the local metal yard, and laid out the design with a scribe. The drip rails are 1/2x1/2" SS square tubing that I milled the top off. I cut out the pieces on my Harbor Freight bandsaw, and cut down the hinges to make the awning sit close to the truck. Everything is TIG welded together.
Here are the finished articles being checked for flatness. I didn't take the slope of the sides into account, and had to cut, bend and reweld my front pieces, then straighten out the heat warps.
