I towed a Dutchman T@da for a couple seasons with a 2014 Escape 2.0 ecoboost AWD with tow package.

Did a 4000km round trip with this combination through VT/NH/ME/NB/NS/PQ, everything from highways to backroads that had some changes in elevation. Only wife and I in the escape and minimal gear.
Overall the combination was OK. It got the job done. I was never white knuckled, or having to put flashers on for the long grades, but I definitely knew the trailer was there and drove accordingly.
I'd wouldn't hesitate to do that combination again if that was the vehicle I had and was not willing to spend extra money to upgrade. However the t@da was a pretty unique TT in size and weight. Something like that is not that easy to come by. I would not go any larger (frontal area/weight) than the t@da even if the numbers made sense.
