Couple questions on a 2021 1880. Surge brakes are working a little too well as they locked up every time I tried backing it into the shop today after pulling it out to wash it. There is a 3/4” lip, but this is the 3rd time backing into the shop, albeit with a different vehicle this time and the brakes kept locking up. I finally had to fab a steel piece to keep the surge brakes from doing there thing. Any idea what is happening here?
Second thing is my 2016 3500 Ram is not recognizing the electric brakes which I assume the trailer has. The boat has a 7 pin plug, but not all 7 are in use just 5 of them. If the trailer has electric brakes, what should I look for. Thanks in advance for the help.
