The key question is: What's the rated towing capacity of the 2014 JGC Limited V6?
Accoring to http://www.jeep.com/en/2014/grand_cherokee/compare/
it's 6200 lbs.
If you can find a travel trailer under that weight (fully loaded), and you setup a proper WDH & brake controller, you should be in good shape.
Keep in mind that the 6200 lb rating is with 1 person (the driver) and no additional cargo in the Jeep. If you're going to load lots of people and gear, you'll have to look more closely and the RAWR (Rear Axle Weight Rating) & GCWR (Gross Combined Weight Rating), among other things.
