New DJ owner. Just bought the 2012 SXT with 3.6. After having read several of the previous posts, i'd resigned myself to the 2500 lb max tow cap. Then I insisted that the dealer supply a print-out relating to my specific vehicle. They did this and are supplying the print-out which states that my DJ, based upon the VIN, is spec'd to tow up to 3500 lbs.
While I still intend to tow a pop up at <2,500 lbs, it is reassuring to know that we will not be at the max.
On second thought, maybe they sold me the 2011 (which was rated for 3500#) but had it labelled as a 2012
