I have towed my 2014 Overland w/Hemi for almost 3 years and before that my 2012. I use a Roadmaster BlackHawk 2 All-Terrain tow bar (I like the additional length and 10,000lb rating) with a RVi2 brake unit. I got the 2014 with the off-road package so it would have 18" wheels as I do not like the ride or wear I got with the 20" wheels I had on the 2012.
This is a great toad and a great trailer tow vehicle. I also use it to tow my 7000lb boat.
