We bought a 2916 Cherokee Trailhawk for a toad and did some research beforehand. Not all Cherokees can be towed - it must have Active Drive II. It also needs to have a Mopar wiring harness installed - we are currently negotiating the installation of this with our dealer.
As far as the vehicle goes, it is quite nice. Lots of electronics to drive you crazy. Also, if you have a bad back, check it out to make sure you can get in/out easily. My DH is having trouble with this because the front roof line is quite sloped and low over the entry. Might also cause problems if you are over 6 ft. tall.
