I also have/use the Dewalt box in your picture. I only use it in my car - not shore,,,mainly to capture salt water dripping. I'll confirm that even though it's glass strand reinforced and roto-molded strong, I still fiberglassed the inside lower part because I also put my 2 Monster LP121 steel tanks inside (Yep they fit!). In the pict below you can see I added a glassed in wooden tank rack on the bottom for both support and to lift it up so the tanks fit over the chest's wheel wells. Tanks in the bottom, wet gear bag on top of tanks & let it drip contained. I completely abuse and pound on this container and it has not leaked a single drop of corrosive salt water in about 150 dive days. I can slam on the car brakes, high speed cornering, and leave it in a hot 140 degree interior and the Dewalt container won't budge/slide/tip. I actually give me more floor cargo space for coolers, dive accesories, etc because all my gear & tanks are stacked high and tight. Lastly I threw the lid out, makes it easier to top load while it's already sitting open in my car. A pair of AL80's will sit inside without the modifications I did.
