No on the Jeep unless it's a 16'. Vintage, 19 still might be ok, but not with a newer Airstream or other RV for that matter.
Vintage wagon with a vintage Airstream or other RV, sure, most wagons could tow a vintage trailer up to maybe 27' depending on engine, wheelbase, etc, maybe more.
There is one person on the forum that does tow a 16' Bambi with a Hybrid. I would NOT tow anything larger than that with any of the Hybrids that are out there, except for say the Chevy Pickup Hybrid, that is a bit more stout than say a Highlander Hybrid.
Bottom line if you are in the 27 to 31 foot range, you should be thinking a wheelbase in the ballpark of at least 130", maybe even a few inches more.
