If you have the towing package that came from the factory ( as an option) , it includes an additional transmission cooler. It also has the sway control that uses the brakes the automatically assist in keeping the trailer from swaying. You can go the the Ford site, where you can "build" the car on their site. Select the trailer package and it will explain was is included. By the way Ford has hidend the wire harness under the rear bumper, to the left of the hitch. It comes with a cover so it's a little hard to find.
I tow a 16' motor boat with no problem at all. Once on your way, you forget you are towing a trailer.
Have a great and safe trip.
