Makeshift bear box

I’ve heard from neighbors that there are bear sightings in the area from time to time. I thought that while I’m camping it would be a good idea to have some sort of bear box. I’ve got a backpacking bear canister but it’s tough to fit much in and if it’s multiple people up for the weekend, forget it. A friend’s suggestion of a jobsite box for storing supplies onsite morphed in my head from a place I keep my tent dry when I’m not there to also being the place I stash my cooler when I am there. It’s 16 gauge steel with recessed locks a bear can’t even touch. Not totally sure it would keep a determined bear out, but it’s better than leaving the cooler out near the tents or locking it in my truck. If it fails I’ll definitely post about that. Assuming I can….
