This project was to make expedition set-up for the rear of the my 2 door Jeep Wrangler JK. I bought as couple of ex-MOD flight containers and restored and modded them. I made a lightweight top that effective binds the two and allows for a second tier of storage above them. I used aluminium covered plastic sheeting for that and 3M Dual Lock strips to hold them fast to the containers. For about a $100 investment it's a decent setup and has served me well thus far. It's quite handy because when at camp you just lift the two containers out, add the top again and you've a sturdy camp/work table.
