The bags in my vehicles are all set up about the same. They have identical basics. i do taylor them somewhat to the primary driver. In my wifes vehicle her bag has her clothes in it and the food is more to her liking. I also have set up a diaper bag for the little ones that can be attatched to her pack should she need be on foot with the boys. I set the bags up to keep 1 person going for 4 days if necesary. But in my mind the bags are there to get me home to the long term supplies. I would strongly suggest when you set up a bag take it out and try it out. i go on 2-3 day hikes to test and modify my set up. You will be amazed what looks good on paper or on the floor of your living room may not work in the field
