Sorry for the long tittle. Wanted to catch the eyes of 24’s out there. So, Ive been chasing trailer fault massages up the wazoo since this thing rolled off the lot thinking a software issue. The constant “ding dong” On my dash drives me Batt $hit crazy! “check lights, check brakes, trailer disconnected, trailer brakes disconnected” All to find out, all my trailers are working fine.

Hello, I am new to this forum and have a strange condition. I have a 2013 Sierra 3500 Denali that I use solely to pull a 18k fifth wheel on long trips.

I have learned to brake very lightly and carefully during this brief period. After 10 or 15 braking cycles, the issue goes away and... Massive brake vibration then none ..read more

From what I read, invisible trailer will work with this if you tweek the configuration. I'm just not sure what makes this better than a rear camera.
