Today I took everything apart and began sanding, staining and painting the wood. I'm going with Minwax "Natural" oil and clear Urethane again.
The oil stain really soaks into fresh plywood. I would recommend getting the 1 quart can if you're doing more than a few small pieces. I also took this opportunity to fill a few extra screw holes and sand everything with 220 grit again.
While that's drying, I'm turning my attention to how to mount up an ARB 2000 awning and possibly some offroad lights. I saw this thread and got inspired:

I liked the idea of being able to remove the awning, and maybe even switch sides. According to the lady at FRP, the sides of the shell are fine for supporting pretty large loads, but it's best to through-bolt the fiberglass and attach through either the steel column that runs along the sides, or steel backing plates. I had requested additional 6x8" plates that they glassed in during manufacture to make mounting a bit cleaner.
Per the above thread, the extrusion in back of the ARB awning is very close to an exact fit with the width and hole spacing of a 2.5" hinge. A 2.5" door hinge is not a standard size. But I was able to find some in stainless steel at Bolton Hardware. The part number is
HY-202525-630-SS.
The hinge is 2.5mm thick, so I went to Schorr Metals (local SoCal supplier) and had them shear me a 3.5" wide piece of 12GA stainless, which is pretty close in thickness.
While there, I had another idea: Roof rack mount. If I could add an artificial rain gutter to the tops of these, I could mount a ladder rack kit or some towers latter. So I also bought 2' of 1/2x1/2x.063" stainless tubing.
The pins on those hinges appeared to be non-removable at first, but it turns out the ends were just pressed in and can be pulled off with vise grips, allowing the pins to be driven out.
Next, I machined down the square tubing to form a "C" shape:
