I have a 2017 3500 DRW with the L5P Duramax. Love the truck but wished the exhaust brake was more effective at keeping my speed down and engine RPM in a reasonable range when towing my 22,000 lb trailer on steep descents. There must be something fundamentally different in the design of the Cummins exhaust brake and the one in my Duramax as I've seen how well the Cummins performs in similar situations. I'm planning to purchase a 2024 3500 dually but would sure like to hear from some of you who may know if the exhaust brake effectiveness has been improved on this new model. I see where there have been changes made to the 2024 turbo, just not sure how those changes translate into improved exhaust braking without excessive engine RPM. Appreciate your comments.
