Good news. Disconnected Solar and for the first time ever i didn’t receive a check trailer wiring error when hooking up. Did a 20 mile loop without any issues. Will have to see what happens on my next trip but i think I’m good now. Going to add a disconnect switch for the solar for now. Easy enough.

Well, isn’t that nice. This is my exact issue. I’ve forwarded this to my service advisor and will be picking my truck up this morning. I’ll get my solar disabled on the rv and do some testing today. Thank you again for sharing. I suspect this is going to help a lot of people out as more of these trucks start hitting the road. Most rvs that will be towed by this size truck will have solar.

Thank you. If i hear anything meaningful from my dealer I’ll be sure to share.

Thank you for sharing this. I do have Solar on my rig. Would you happen to have a link to or a photo of that bulletin?

Same issue with 24 3500 DRW Denali. Hooked to fifth wheel at 500 miles and it started randomly throwing the check trailer wiring error and disabling the trailer brakes. Brakes usually stay off for about a minute before coming back. We’ve checked everything on the trailer including replacing the 7 pin with 2 different styles of new plugs. Nothing fixed it and it’s seemingly random. 800 mile trip and it cut out on me twice on the way and 4 times on the way back. Has 1500 miles on it now. All lights and everything else functioning fine. Just having issues with the brake controller. Pulled wheels and hubs and checked wiring and brake magnets. All good. Good continuity on all wires. 2022 F350 had zero issues with this same rv. Rv is a 2023 337RLS. Truck is currently in the shop. Haven’t heard anything yet. Not feeling optimistic.
