Nice list. Always nice to have some just in case items. Better to have it and not need than vice versa
Being a transplanted to Texas Viking a few things I used to carry with me in my trunk in addition to some of your items listed while hunting or Ice fishing in Minnesota are.
Knife and an axe
Candles and a coffee can
5 Gal Plastic Bucket
Firestarter such as a magnesium or firesteel type
Pan of some sort to melt snow
A small self igniting propane torch (One of the best things I've ever used to start wet tinder)
The nice thing is most of these will fit in the above 5 gallon bucket and still have room for more.
