We recently added disc brakes and IS at MORryde to our 2017 365 Syracuse, Trail-Air hitch. I have a 2015 GMC 3500 DRW truck with built in controller. What setting are recommended for the controller? I have tried several and find my fiver is bucking when I apply the brakes. I was told to drive unit to a gravel road, drive forward and then brake, changing to a level where unit slides then lower setting one number.
