6.7L Cummins VS 6.7L Cummins HO

The Aisin might be better but I regularly tow 15 K in the mountains with my 68 RFE and I give it hail! I fear nothing about this transmission!

Yep, kind of the way I feel about it.

All you have to do is hope yours gets fixed before it fails. :) That was one of the reasons I didn't look at anything newer than a 2018 when I bought.

Well Ram decided to go back to the CP3, and issued a recall on all 2019 and 2020 Rams with the CP4 to replace with the CP3.

Yes but watch out for the exploding fuel pump

The HO engine has a little lower compression ratio, so, the regular output will be a little better on fuel when not towing. How often will you be towing and how much weight?

For those of you that have towed with both the High Output Cummins and the regular Cummins was the HO worth the extra $2800?

Yes, as a bonus you get the Aisin HD transmission.
