Traditionally I've carried tools and recovery gear in two plastic tubs and other stuff just laying around.

(Toolkit, tire repair kit, winch remote, snatch blocks, bow shackles, gloves, air compressor, first-aid kit, tree strap, tow strap, chain, tire iron, duct tape, ratchet straps, paper towels, cargo bungee net, awning wind breaks, and camping chairs.)

I've found they take up too much space so I've come up with this design to store the same items (plus more) in a more compact design. This involved some fabrication.

I fabricated a frame out of square tubing and flat bar which mounts to the spare tire mount and two factory screw/bolt locations on the body.

The MOLLE panel was purchased as a different design, but it still works fine for this.

Once that's in, add a JCR window MOLLE panel and a couple of RotopaX storage packs and load it all up.

There's significant space-savings with this design and so far I'm pleased with how it turned out.
