I hadn't thought of it but Nomad has a point I've got a few large coolers filled with gear. I've had them for many years and they hold up well, especially if you keep them out of the sun. They aren't Mil-spec tough, if you want hard-core tough cases run the term 'mil-spec case' through your search engine, but they have been sat on, used as workbenches, and absorbed a lot of abuse without failing. Catch them on sale and they are pretty cheap.

Larger ones are suitable for handling that recurring problem; getting rid of the bodies.
