I have a Ford Edge although it is a 2007 model with 59k miles. Love my Edge!
While your Ford will tow either TT you're looking at, MOST DEFINITELY you will need a WDH system with anti-sway. I wouldn't even consider not having one.
Coming from towing a 10' popup where I barely noticed the trailer behind me, I definitely notice the 16xrb behind me. I think the difference is the wind drag and extra 1,000 lbs compared to the popup I had. The anti-sway keeps the TT steady when big rigs blow past me, among other things.
I looked at the models you're interested in and was concerned that I would max out my tow rating.
The Edge tows mine fine, I take it slow and easy and on inclines it doesn't bog down too much. I do notice the gas mileage difference.
I don't overload the TT with "stuff" which I think helps alot in performance and safety.
