Watch your fingers
Got back from a 3 week trip and the box worked great. My box has a top and a bottom compartment(not a drawer). The doors were attached with self tapping sheet metal screws. The only problem I had was the bottom screws come into the compartment right where you place your hand. This can result in a nasty gash to your fingertips. I removed the sheet metal screws and replaced them with 10-24 bolts and nyloc nuts.
