I have put many thousands of miles on my 2017 QC 2x4 RAM towing dump trailer, often at or near max GCWR. It is the pentastar with 3.55 rear. My question is, what would you all think would be the better towing setup, my current one, or a Hemi with 3:21? I understand that numbers on paper show the Hemi with a larger tow capacity, but has anyone here towed with both engines, and those gear ratios? I am in a predicament for my next truck, I know i work the pentastar to capacity, but i LOVE the empty fuel mileage. Im afraid that the hemi with 3:21 would just lug with 6-7k behind it. My pentastar, with the 3:55, while isn't a Cummins with 4:10s, does ok by me.
