One concern may arise. When we had our Saturn as a towed, applying the brakes hard in the coach would lock up the Saturn's brakes many times. Of course the Saturn was so light you didn't know it was back there.
The10 and the 13 Edges no problems bu this new 19 Edge ST has larger and stronger brakes.Though a bit smaller is is about 400lbs heavier than the 13. Proportional response is the way to go.
I looked n line at install and activation of Air Force 1 just a bit ago this evening. AIt still activates by the pedal arm.
I had thought it worked on the master cylinder or brake lines.
Looks to be the only two games in town it and Roadmaster. I thought there were more options.
