Very good cosmetic condition. Includes braking unit and remote controller unit. No breakaway switch included. I tested the unit in the front seat of my Toyota Highlander. It powered up and I was able to initiate the self-calibration. Once calibrated, I cycled through each of the functions using the remote switch. Check out the short video. This is from the estate of a elderly couple who no longer use it. I have not tested it in an actual towing scenario, but they did confirm it was working when removed from service.
