I just towed my 15,000 lb RV 5th wheel from Tennessee to Florida. I have a 2020 3500 DRW Silverado diesel.

I used the Trailering Option and set my Trailer Gain to 6.0. 7 Pin plus connects my installed truck brake controller to my RV brakes (drum). I drove 60-65 mph and all was fine,  even had rain and storms. Hope this helps Benny. I did need the manual option of shifting to L and adjusting the + - on the Shifter. Benny

My 2020 3500 does not work with my EOH trailer.  Been an expensive battle replacing everything on my trailer to find out that its been the ITBC all along.  GM said my truck was fine and had to be my trailer.  4 trips to the shop and turns out you need an adapter installed on the trailer to get it to work with the factory ITBC.

I have a 2022 GMC Sierra 3500 DRW, pulling a texas pride gooseneck flatbed trailer.....electric over hydraulic brakes. 

The ITBC isnt working for this trailer. I too have had 3 trips to the GMC dealer and one to the trailer shop. 

Still trying to figure out if there is something I can do short of replacing the controller. 

 

any suggestions?
