np! What size travel trailer? Mine is the Lance 1995, dry weight 4100 with dual axle. Being that I have 4 brakes behind me, I would hope the update helps. But like I said, not holding my breathe. The camper place showed me the Curt on Friday when checking out, and said Curt just came out at the end of 2018 I think, and people really like them a lot. They were asking about $250 for it (camper store retail). Online looks like the run about $50 less. I haven't had time to research them yet, but seems to be the new big thing. Its wireless and your phone controls the settings. Worth considering since I need an extra 2-3 inches with the Tundra. That connector is so high that I had to get an extension for my boat too.I saw your post about the Curt option and misunderstood; thought you had “found a deal” so to speak.
The update changed my brake controller from scary worthless to functional, I don’t see why it would be different with your truck. Good luck! I’ve towed a travel trailer at least a couple thousand miles since the update with zero issue.
