I would not tow either of these TTs with the Jeep, in fact I found this in a review I found on line
"Liberty CRD's extra torque can't be fully used. The vehicle is limited to the same towing and hauling maximums as the gas model: 5,000 pounds and 1,150 pounds.
Jeep's worried that elevating the towing maximum would encourage people to hitch up long, heavy trailers and the tail would wag the dog going down the road"
Both of these TTs, when loaded will easily tip the 5000 lb mark - and don't forget that you must also subtract the weight of passengers and cargo in the Jeep.
I would be looking at something in the 18-20' range with a GVWR of around 4000 lbs. - or perhaps a pop-up or TrailMannor - low profile trailers don't have as much problem with sway due to winds - however it is still possible to have the tail wag the dog.
