My 2020 RAM 3500 Cummins has the 4.10.More cost effective?
I similarly equipped Cummins Laramie comes in at basically the same price as a PW. Now add all the PW or aftermarket bits. None of that will be covered under warranty. I'll give you the benefit of the doubt that you'll be doing all the labor yourself and that your time is cheap
I don't think you can get the 4.10 in the cummins or the 8 speed trans either.
It would be a sweet ass truck for sure, but definitely not more cost effective.
