well if your stuck in winter then the water that you pack,,might not be water anymore,,, your better off bringing some way to keep yourself warm and melt snow ,,,or melt the frozen water that you packed . Im not really sure how long water "lasts" when its packed in a car?, does it go skunky? i know at work (in the shop) the water in the pipes going to the shop does not take long to get a real bad smell in it in the heat. I suppose that in the winter time water might last longer in a car ?
heat is your 1st concern i would think . if you have heat you can melt snow for water. and you can cook whatever you have . without heat being stuck in the snow is not too pleasent
i dont carry any kind of survival kit in my car ,,but if i did it would be a gallon can of white fuel(coleman) and my single burner coleman camping stove . with that i could heat the car up every couple of hours for several days ,,while melting water,,heating food
