I disagree on the jerky/dehydrated/AddWater foods for trunk storage. Why store dry foods when you can store canned chili, ready-to-eat canned soup, and other foods that also at least partially serve your need for water? If you’re not going to carry it, foods with water are usually a better option, at least based on my tastes and preferences.

"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....

Bingo. Having to boil water to eat in such an emergency is just silly. For some obscure reason, those talking about emergency foods in car or home almost universally talk about dehydrated stuff, possibly because of the weight. Simply not relevant in such a sitution.

if you could find enough dry twigs and sticks lying around to actually build a campfire each night, but this will be impossible in a blizzard or heavy rainstorm.

Entirely possible if you combine the twigs and such with one of these.

Indeed. Campbell’s Chunky soups are filling, delicious, nutritious, and easy to eat cold (just add a spoon). 9 of them take little space in a trunk, making 3 meals a day for 3 days. Heck, 90 of them fit a trunk easy, a month of food. Don’t underestimate the capacity of a car; make it easy, don’t store “difficult” food if you don’t have to.
