I try to keep my chainsaw in the vehicle during winter. This last storm we had no power for 6 days the reason was due to fallen trees. TONS! W/out a saw I would have been trapped in my driveway, and then on my street, and then the main street, etc, etc.

Another important thing for us during winter is to keep snow boots, and heavy-duty blankets in the vehicle.

Most of the rest of the gear is universal.

Extra batteries and flashlights maybe since so dark now but nothing really special.
