Re: Looking for real world towing numbers...
I just dragged my new (to me) 25' Airstream from Salt Lake City to Long Island. The Airstream weighed about 5,900 lbs, with a tongue weight somewhere a little north of 800 lbs. The Jeep handled it beautifully, including going up Sherman Hill in Wyoming (as it was my first tow with a travel trailer, I chickened out on the 6% Parley's Canyon hill coming out of SLC, but in retrospect I'm sure the Jeep would have done fine). Seriously, if I didn't know the weights are an issue, I wouldn't think twice about keeping the Jeep as my primary tow vehicle forever. It was a total pleasure.
The issue you run into is payload - the tongue weight of your trailer counts against you, as do all of the carbon and water-based forms in the Jeep's seats. The Jeep's max payload is just enough to safely carry your trailer, you, and likely nothing else. Yeah, nothing - and nobody - else. And the max hitch weight of 720 lbs, while (in my opinion) arbitrary and probably way too conservative, will probably rule out long-term use as a tow vehicle for such a trailer.
I intend to use the Jeep for the next couple of years because we won't be traveling often and we won't be going on long trips. But once we retire and head out for longer trips much more often, we'll pull the trigger on a better-suited TV and use the Jeep for the jet-skis and boat.
