The Furrion camera mount on my 2015 F265RBSS is powered via the marker light circuit, powered from the tow vehicle. It worked great until I purchased my 2019 GMC Sierra and GM went to this "awesome" PMV system for trailer output. This system doesn't provide the correct power to operate the camera, but the trailer lights work okay. Furrion has come up with an inline adapter to go between the truck & trailer which then sends 12VDC properly to the marker light circuit and it'll operate the camera again. I'm just not sure I want to spend more money to make it work....
