We have had a 2007 Hemi Commander (XK) since new. 112k miles. Virtually flawless. MPG averages around 15-16. Have hit 19mpg on longer highway trips. Best automatic 4WD system I have ever used. QD-II (standard with the Hemi) gets you full lockers front and rear (auto - not selectable). We had a few minor issues with a leaky sensor and sticking rear caliper. Rear DS probably needs new u-joints now but they are not serviceable

. I have used it to tow campers and my tractor quite a bit. No regrets from this owner. We hauled a camper and the whole family from northeastern PA to Wyoming and back in 2010. Not a single hiccup.
Research your intended vehicle, no matter what it is, and drive them both. Make your decision based on your own observations, not the ones sourced on the internet (including mine).
BTW - Sergio was not even part of Chryco when they developed and sold the XK. The Commander actually sold rather well, but cannibalized sales of the GC, which had a substantially higher profit margin due to its maturity. The XK is essentially a stretched GC, so to say it was "unfit for human consumption" is a bit absurd. They use(d) the same suspension and driveline.
