6.7 Cummins vs 6.6 Duramax
As someone who knows next to nothing about Diesel engines, I am trying to figure out the strengths and weaknesses of these to. Any opinions would be appreciated.

I have a 2015 Ram 2500 with a 6.7 Cummins and love it. Our bus company also has a Freighliner bus with a 6.7 Cummins and several more with the Duramax engine. Frankly, both are excellent engines and very reliable. I'd go with the best price/dealer service option.
