I also plan on towing a 2013 Edge and am aware of the battery discharge problem. I have considered using the hot wire from the tow wiring plug to attach to the Edge positive terminal. The wiring harness is already grounded becasue it is used to run the turn signals and brake lights. Do i still need to run a wire from the chassis battery negative post since the coach is already grounded to the toad?
I have also considered the toad charger product. Is this necessary?
