I have a 2022 6.6 gas, 3500 CC, SRW. As stated above, it only comes with the 3.73 gears, no 4.10. I was a little worried about this, but I am please with performance.
I do not tow a heavy trailer. To date, I have towed a 7.5k travel trailer and it towed beautifully. The "tow" mode keeps the transmission from hunting and it is very quiet. Gas mileage is 14 mpg, compared to 10.5 for the 6.0
The new truck is significantly quieter than my 2019 3500 with the 6.0.
If you have specific questions, send me a PM

yeah but what is the mileage difference when towing.
