In the Pathfinder I just left it in D but it was a 4-speed auto so it generally stayed in first or second gear. In my Subie, I'll lock the center diff and keep it in 1 to 3, but its geared quite short. Keep in mind, I'm talking about making my way down an unplowed road with deep-snow, going 15 to 20 km/h. In my way of thinking, its all about maintaining forward momentum, and better to be in low gear where you can muscle your way thru.
After one of the big storms last winter, I made it down the road here at work which had yet to be touched by the city using this technique. Belly of the Subie was dragging in the snow and there was wheelspin, but she made it. Guy in a CR-V didn't even make it 20 ft. Snow tires and locking center diff, I guess.
I haven't driven the Rogue in what I would consider deep snow yet, but my reasoning for putting it in manual is I don't want the CVT to misinterpret "More Power!" with "Go Faster!". I want to go relatively slow in a low gear with a decent amount of RPM. I also plan to lock the center diff and turn off the TCS when I encounter these situations. I am talking about situations that only occur 6 or 7 times a winter. The vast majority of time I plan to just leave her in D with all the safety systems on.
Starting off from a stop at a slippery intersection however, I generally short-shift and get into the higher gears quickly to avoid too much spinning and fish-tailing.
