Your X does kickass in the snow. I am in Alaska and it is one of the best trucks I have ever driven in the snow. In that situation with a 6spd I would put it in 4HI and 2nd gear with VDC turned off. Your X would walk up that hill. The VDC is what reduces the wheel speed. With that turned off you can spin the tires as much as you want, but the limited slip (ABLS) will still work.
