Snow is not what you worry about, it is the slush and the ice that matter.
#1 - Always be prepared. make sure you have some sort of emergency kit, candle, flashlights(plural)with extra batteries, a couple blankets and some food. The blankets may not be for you by the way.
#2 - Make sure that you dump your air often.
#3 - Don't assume that people can see you, even if you weigh in at 30,000 lbs and four times bigger than they are - always assume that they will hit you before you hit them.
#4 - Make sure that your tires are properly inflated or just a little under inflated.
#5 - make sure that your coolant level is up to the proper level with the correct type and mixture of coolant.
#6 - Change your wiper blades going into winter and again in the spring. Make sure you use the proper washer fluid and remember if you do go add the alcohol to the mix, it will shorten the life of the blades and hoses if there is too much in the mix.
#7 - If it is sleeting, crank up the heat and find a place to safely park and wait it out. Sleet is freezing rain and freezing rain is just that Freezing so it means that ice will form everywhere, the mirrors, the antennas, the grill, the traffic lights and the road. A lot of mixtures used for snow will not work on pure ice.
8 - Wash your truck often.
