2024 Grand Design Transcend running lights

[DonIdd]

I purchased a 2024 Grand Design Transcend 265BH. The Furrion back up camera and running lights operated okay when connected to my 2013 Tundra. Since towing weight was an issue, I replaced my Tundra with a 2020 GMC Sierra 2500HD Duramax diesel. Now only the brake lights and turn signals are operational on the trailer. The Furrion camera and running lights do not function. After researching LED lights power demands, it was recommended to get an adapter bypass unit to resolve the issue. I purchased the following: Furrion Vision 7-way adapter (F2BC004XXBK), and from eTrailer 7-way trailer adapter for towing LED lights (C57003) and trailer connector adapter with lamp out sensor bypass (20142). None of these adapters fixed the problem. I know others have had the same issue with late model GMC and Chevy trucks. Recommendations? What next?
