I have a number of those aluminum cases. I used three of them for storage on my recent trip. Two fit side by side in the bed of the M416 trailer. They are a bit heavy and if you're not careful the spring loaded latches can get ya a cut or two if you're not paying attention. I figured they would at least be bear resistant. Definitely rodent proof. Next time I'll use action packers storage bins for the weight reduction and band aid savings. I still like the boxes and agree they would be good for storing other items if the seals are still good. If the seals seem a bit dry use some petroleum jelly to soften them up. I had 100+ freeze dried food packages in one, and the other was for my kitchen. It holds a Coleman suitcase stove in one end, and it's a very nice fit.
