What do uoy all use for food storage to keep food warm, like here bestvacuumflask.com? I normal just throw the big stuff in a milk crate and call it good, but after an ordeal with some oreos and ants ...
Back in the days of tent, I bought some of the containers that have the hinged 2 piece interlocking top. I put sheet metal dividers in them. Closed, I would use bolts to hold them closed against 'coons. Flat to transport, or stack, stand on end the dividers are shelves. BTW, when packing for trip, we bring into kitchen switch open packs for new ones I totes. When home, restock the totes before store in basement. In emergency we have food packed.
