To add to what was mentioned above.
If your gonna mainly use it for driving around in the snow your mainly going to use 4hi. With the locker on the offroad models you have to be using 4lo. So going with a lesser trim will save ya some cash and you can put that towards some better tires.
I use my 05 in the snow (even with the stock long trails on it) in the snow and it does just fine and haven't had a problem yet..
