Don't do it.

2009 Jeep Liberty Limited 4dr SUV 4WD (3.7L 6cyl 4A)
Folks got it as a B-day present for me. So it was free and I still don't like it. I drive in -40F temps, the heat often doesn't get the job done on the feet or the dash. I've actually had ice form on the inside of the windshield. Dealer says "Nothing they can do about it." So it's definitely not good for colder climates.
Towing ability. This thing tows beautifully, only good thing I can say about mine.
Fuel Mileage. Better placement of fans/heat on windshield & feet. Legroom is terrible.
