standard issue in my family, is antifreese and water, and enough for one total oil and coolant change, with filters, etc, then a 50lb bag of tools, and snow gear, shovel, wood, and stuff like that. Carry extra clothes.

we drive around with studded snow tires, and I love them, they are great, someone I know (hint) drove the studded tires up to 100mph with only one stud wripping out, not too bad. Tieing down everything is important like it was said, but why put in sand or something useless, instead of like tools, and stuff like that. I would bring kitty litter thats thick so that you can use it for traction or something.

My winters arent too bad, I just live in the mountains, so sometimes it snows and ices up then a few days later its gone, so I dont know it all, but thats my advise.
