2x "BUY GREAT TIRES"
I run studded Nokian Hakkapeliitta. The studless tires have come a long way but for the transition zone before you get to nice compact snow, the studded, sipped, soft rubber compound version has more traction in the black ice situations. The truck TC combination handles slush really well.
Like everyone says slow down, no lateral g's when cornering. Smooth inputs to the accelerator, brake or steering wheel. Try and straighten out the curve on that icy overpass or bridge.
I like driving late at night up to a ski resort. Less traffic. DOT has a chance to sand the road and you know it is below freezing, so there is no question that what was water is now ice. Drive accordingly. At night it is also easier to see the edge of the road or the snowplow pile in a blizzard with good fog lamps, whereas during the day it is all just a white out.
Going uphill isn't an issue with 4WD and the TC in the back
Going down hill under most conditions I leave my exhaust brake on. However if it is really icy or if it is raining on compact snow I'll shut it off and use the brakes lightly to slowly descend.
I also carry dry sand in old gallon container in the truck. I use it in the situations where I'm forced to stop going uphill because cars have lost it and blocked the road, making hard for me to restart. I just open the lid and make a 6 foot trail in front of each tire, you don't need to use much. I then walk up and do the same for the car that tried to pass the mess and is now blocking the lane. That gets them going and out of my way so they can put on chains and I can get going without having to resort to chains. The lidded container seals the sand up nicely after you use it and keeps it dry, unlike a bag of sand that gets everywhere and wet.
Snowy roads are easy to drive on if you are prepared and there is no reason to be drifting sideways in your TC. Even icy roads can be navigated safety with a combination of good equipment, good technique and judgment. If it was an east coast ice storm I'd stay home or wait at the resort until things got better, as I always carry extra supplies.
If you are winter camping more in the dead of winter, have a contingency plan for various things that go wrong. Propane autoswitch valves not switching, furnace running a lot more and draining a marginal sized battery bank or old batteries, or getting stuck at a resort due to a road closure.
If you are at a resort and get a big winter storm, a shovel is really nice, as is a safe way to clear off the roof near your vent. Once more than a foot of snow is on my roof the warm air coming out the bathroom vent makes a chimney in the snow, unforturnately the warm air from the black and gray tank vents do the same and join together to make one big smelly chimney. This less than pristine air then comes back into your TC when you turn the fan off, unless you clear that section of the roof.
Spend time this fall insulating and sealing openings (the air conditioning and stove vents are just big holes to the outside. We can go about 4 days on a tank of propane with the camper at 70F inside when it is -10F outside. Makes my girlfriend really happy. We run the propane while traveling so the camper stays warm and doesn't get a chance to cool off. We don't winterize and enjoy using water. The pleasure of being comfortable and warm while parked at the base of a chair makes one forget about the worries of the drive up.
We ski about 70 days a year and have visited over a hundred ski resorts in our TC without going off the road, nor drifting out of control. We still have a lot more to explore. There are at least 241 ski areas in the western US and Canada so think about a winter road trip when you get tired of skiing on icy east coast slopes. Just carry a PLB, as out here there isn't great cell phone coverage if something happens.
