How do you connect a tow dolly with electric brakes to an RV with air brakes? The coach is an 05 Fetwood Providence. Is it possible that feature has been added to the rear plug when built and the system knows when it is connected? BTY, new to rving. Have put 500 miles on it so far and slept in it 3 nights. Really enjoy it.
