Hi Alan! I recommend the Redarc Tow-Pro Liberty Brake Controller # RED52VR for your 2015 Freightliner M2 106. This proportional brake controller is simple, reliable, and won't take up space in the cab of your truck.

Your M2 is likely equipped with air brakes, so the main thing you'll need to verify is that the truck has the necessary wiring for an electric trailer brake controller, including a usable brake light signal and brake output wire running back to the 7-way. There isn't a custom plug-in adapter available for your Freightliner, so the # RED52VR will need to be hardwired into the truck.

Where are you headed once you get the Freightliner set up for towing?
