I had a 2020 6.6 gas reg cab dually. I towed 15k lbs (gooseneck with round hay bales) many times. It was in Michigan. No issues, and had experienced some uphills from a stop.

I fell into that with my enclosed trailer and 2003 Silverado 1500 4.8L. Towed it great around town. Acceptable for 50-mile trips. After the first 200+ mile trip, I knew I didn't want to do that forever.
