Need to cook, even better if you grind your own meat, basic maintenance on car nothing fancy, oil swap, tire swap, spark plug change filter change basic shit, be able to set up a tent innawoods and make a fire with steel and kindling, be able to fish, be able to diagnose and fix your heating and radiators mostly venting and temperature gage, you need to be able to swap out the vaccum cleaner bag, to iron a shirt properly, polish boots, tie a tie, clean out a sink properly, fit copper piping, although might be overkill.
You need to be able to fill a tax form, know how to saw planks, hammer a nail, screw in a screw and preferably how to do basic wiring, top up your heater with water, be able to use and apply a tourniquet and bandages (you should ALWAYS have a tourniquet, reflective vest and clamps in the car you can skip any other precautious thing),
Basic foraging can be good picking mushrooms and berries and drying it will save you a lot of money or it does for me, I manufacture my own drugs too but that's more hobby then a necessity.
That's all I can think off off the top of my head all good basic stuff you will use if you live in a home that anyone can do and learn.
