I have a 2008 Limited with Skyslider I bought new from the dealer. 144k miles (and another 40k+ flat towed behind my RV over the years), and mechanically it's great. Early KK's had issues with improperly ground cylinder heads, and I've had the Skyslider fail twice in the first five years (ChryslerCares split the costs with me, but still cost $3k each time), but since I do all recommended maintenance on time (or early since I tow it) and never had it leave me hanging. I did add the K&N intake and filter package (not available in CA) and though I lost 1 MPG, I actually have some POWER!! Once that engine can breathe, it's golden! I still get the 'mystery ding', but that's been since I bought it (ding, but no error codes ever show on OBD2) and the MyGig radio will occasionally return to whatever album I was listening to on the HD before my current album. (So, if I listen to Boston on Monday, and Styx on Tuesday AM commute, when I go home Tuesday evening it restarts Boston.... and can happen anytime with any file...) The interior is very pristine, except where the Skyslider has leaked road-spray around the header a bit, and where my German Shepherd took a bite out of the leather back seat. **** warmers are still toasty (and used often as we live near Seattle) and everything else electrical has been good. Overall, except for mileage and road noise (from Skyslider) I've always been happy. (But I have a vent deflector just forward of my 'slider that cut wind noise by 50%. Hope this helps and happy motoring!
