I had a 2020 Silverado 3500 regular cab dually with the 6.6 gas. I had it for more than a year. I never pulled in mountains, but I did pull a hill from a stop at the bottom with over 15k pounds without a problem. Fuel economy was as stated earlier.
I never felt that the 6 sp transmission impacted performance for me. I have also driven a 2021 3500 Crew with the Duramax. And yes, it did better.
Not sure what I will order after I tow my travel trailer next week to Iowa with my van. I expect that the comfort and trailering capabilities of the new trucks will convince me to place the order.
Weird news coming from the guy who’s been pimpin vans as awesome tow vehicles….
