Traxion mats and shovel are standard items year round. (once forgot to take it out in the spring and I used it to dig my car out 4 times in a row). Blanket, whistle, flashlight, candles, firestarters, mess kit, water, etc. are all there year round.

The only main difference are the snowbrush and ice scrappers. I also lubricate my locks, use a special rubber stick to prevent my doors from freezing shut and change my washer fluid with a higher freeze protection version.
