I've just started to tow a 2013 Edge SE AWD this year after using a Honda CRV for a couple of years. No fuss towing, same as CRV, run the engine 5 minutes, basically go through the gears according to owners manual and then in neutral, turn off and tow.
We really like the extra room in the Edge and the driving/handling compared to the Honda.The base plate was available from Amazon.ca for the same price as in the US with free delivery (this was in May).
I also have a 2013 Ford Fusion Hybrid that can be towed four down and may put a tow plate on it next year. Great gas mileage currently get 60-65 MPG (imperial gallon).
