Recently picked up a couple of surplus flight recorder cases (at least that's what I was told) to use as a storage. Case is water tight, air tight, and foam lined. I trimmed down the side foam, cut the bottom foam to fit a 4-way, tow strap, pulley, and small case of misc. stuff. Also, foam cut the top to fit my winch control and air gauge. Enough room left to keep small tool bag, air line, and ammo case with fluids. Enough room to keep my essentials. Still need to decide on hard mounting in the JK and mount the Co2 tank.
