"I disagree on the jerky/dehydrated/Add-Water foods for trunk storage."... you make a good point, so I'll point out the author's plan was a kit that could fit in a small cooler that could easily be carried.[plus boiling water is easier than heating a can].

In my area water is easily available so you only need a container and a micron filter but desert/snow areas would be different....

In a real survival situation, you don’t need to heat the can but can eat it cold. I speak from experience - I was sick at a hotel once with no room service AND no microwave. I went to the drugstore, bought a can of chicken noodle soup and ate it cold. It was a little tough at first to choke down, but it helped me feel a little better.
