Haven't towed with it, but I've put about 15k on my company's work vehicle in the last year, a 2014 Explorer Sport. The ride is a little stiff, and I am old enough that I prefer the cushier seats in the Limited over the boards in the Sport.
That being said, I love the fact that the EcoBoost makes that tank of an Explorer go like stink! 12PSI of forced induction makes a night-and-day difference compared to the naturally aspirated motor that was in the limited I had a couple months back as a loaner while my truck was in the shop.
I would think that towing-wise, it would do about as well as the last-gen Explorers in terms of stability.
