Hi Bob,
The Edge has towed fine, actually towed it over 7,000 miles on an out west trip this past summer.
We like the car very much, its comfortable, handles very well and does great on fuel.
I am coming from a Ford Escape 2009, 2010 and 2011, 3 cars, 3 years, 11 transmission failures, and 3 Lemon Law battles before I ended up with the 2013 Edge, so I was very uncomfortable at first towing this car.
I found myself starting it and running it through its gears when I stop for fuel just out of fear but on those days when I didn't do that and dragged it around for a full day, at the end of the day the car would not start because the battery went dead.
On this 7,000 mile trip I did that twice and twice I ended up with a dead battery.
When I was purchasing my 2013, I was told by Ford that the 2014 Edge would not be Flat Towable, have you verified it is?
Good Luck.
