Winnipegger here. I've had a 2007 Sport, a 2012 Sahara Unlimited and now a 2014 Rubicon Unlimited. By far the best winter vehicles ever!
The heat is ridiculously hot despite the -40 outside and the 4x4 can handle any blizzard dump of snow.
My tips though;
- upgrade the headlights the day you pick it up. Just do. Don't ask why.
- keep in mind the roads aren't always covered in ice but I typically switch to a good mud/snow tire (Duratracs are good) for the winter. This year, because of the stock rubicon tires, I will be getting a more "winter" tire and swapping back and forth
- keep tow straps, jumper cables, etc in your Jeep. Not for you, but to rescue your idiot friends driving civics.
