For those who live in areas with harsher winter weather, you'll be happy to know that a new track system has been developed for the JL. Pricing has been se just under $10,000, which is about half of what I've seen from other companies. https://rubitracks.com/
Think about the lift kit and tire setup you could get for that kind of money, multiple sets even. Are they really that much more capable over a traditional setup? I've never really seen them in action.
