Wow, I'm not picking on anyone but your emergency kits must be HUGE!
When you review something like this it's important to take a backpacker's view on things and figure out items that can serve MULTIPLE FUNCTIONS that way your kit stays kinda compact and will be a LOT more flexible.
Now I'm basing my thinking on vehicle stuck, lost, etc type of stuff not TSHTF where you are trying to hide out.
#1 item. A basic kit and
working knowledge of first aid. Life threatening injuries must be taken care of first. There are literally THOUSANDS of websites that will help with what should be in a first aid kit and the red cross courses are excellent.
#2 Having multiple methods for making a fire and knowing how to go about it is vital.
-Fire is a SIGNAL. If you can signal and quickly get someone's attention then the rest of the stuff may not even be needed.
-Fire is COMFORTING. Especially when it gets pitch black and the night animals start making noise and shuffling around in the brush.
-Fire is WARMTH. A little insulation from the ground, some reflective material, and a decent fire, can keep you alive and possibly even comfortable under some pretty RAW conditions.
For example, this is the setup that got me through the night in relative comfort when the weather on a mountain top unexpected dropped from 60 degrees to 18 degrees (I had packed for a low of 40 or so).
A lot of old leaves piled up under the blue tarp provided insulation from the ground. (Heavy grade contractor's garbage bags slit open and laid flat would have served the same purpose). The Space Blanket clothespinned to a string run between two trees gave me both a windbreak and reflected a lot of the fire's heat onto my sleeping area. It would also have helped shelter me at least some had it started snowing but in that case I would have taken my trusty knife and started assembling a lean-to type shelter, returning to warm up as necessary. The sleeping bag was too light for conditions, but after I got this setup rigged and the fire going the sleeping bag was actually too warm with all the reflected fire heat.
All of this rigging is with no vehicle available. If I'd had a car (especially a hatchback type, I'd have had a great shelter that I could have directed reflected fire heat into and probably have been downright comfortable <grin>.
