> (In reply to bluesgiant) Have you considered how cold it will be sleeping in a metal box, even with a sleeping bag etc??
One presumes the op is talking about an emergency situation,
Perhaps there could be a case for modifying these boxes to have a foldable compartment for shelter, without emptying the contents, but only in truly remote locations.
There is just about room to get a person into the CIC hut equipment compartment which is open, without putting all the gear outside , but again in an emergency, not just for laziness.
