I have a 2021, 2500 HD, after initial picking up from dealership drove to Florida and back pulling a fifth-wheel (14,000lbs)
I have the diesel motor with tow package and have the exact same issues. I cannot pass anyone as it will not drop down a gear to pass, and when driving through small towns at 25 to 30 miles an hour it seems like it's going to die as it will not drop down a gear.
I have tried it both ways with Towing on and off with no change either way. It's at the dealership as we speak and they're saying there's nothing wrong with it. Should have stuck with the 2006 Chevy Silverado, had no issues whatsoever pulling the same trailer.
Any help and or suggestions would be greatly appreciated.
