There's nothing quite like camping in the snow. I've done it in a tent a few times. It is incredibly quiet (unless your teeth are chattering). There are no bugs out and the sound of their little wings flapping that is so present during summer camping is noticeable absent. It would be quite a luxury to do it in the Westy.
A couple of tips I'll pass on since you didn't ask:
- 1. bring along a piece of closed cell pad to stand on or put under your ass if'n yer sittin in the snow. It will help insulate your feet and keep them far warmer.
2. A nalgene full of hot water (cap on tightly, please) at the foot of your fart sack keeps the tootsies warm most of the night.
3. don't forget TP--wiping your ass with snow is both cold and messy.
4. Don't forget your chapstick or sunscreen. The sun and dry air can hurt ya.
5. Bring a book--the nights are looooonnnnnggggggg.
6. A good warm hat is your friend.
