6.7 Cummins vs 6.6 Duramax

I would expect when the newly designed 2020 Gms are available you should be able to get a very good deal on a new 2019.

Most likely a new 2019... unless I can find a new 2018 still laying around. Maybe I can find a demo unit that I like. That would probably be ideal.

Are you buying new? 2020 or 2019?

I want to thank you all for your thoughts and comments. Now it’s time to try to get the best deal that I can :-)

I never did like Dodge trucks and they had their fair share of problems during that time period. How many times have we seen the comment "unfortunately, it's a great Cummins engine with a Dodge wrapped around it". However, about 2010 major upgrades were made to Ram trucks and now they're one of the best engineered and most reliable trucks on the road. Four years ago I bought a 2015 Ram 2500 CTD and it's absolutely the best truck I've ever owned. That includes five Suburbans, a 7.3 diesel Excursion, two Ford E250 vans and a Ford E350 van with a 7.3 that I ordered new.

Frankly, it seems that we're at the point where each of the "big three" build really great HD pickup trucks and I'd be happy with the offering of any of them. Anymore, it comes down to the price and the quality and reliability of the dealership service as to which one is the best truck.

i went with Ram/Cummins and have loved it. i chose Ram because i liked the look, the cummins/aisin combo had a reputation for durability, and on the highway most hotshot drivers were driving Rams. they love the durability of these engines and the ease of working on them. i pull a loaded tt uphill in 100 degree heat like it is nothing.

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.

In the end, when the 3 truck brands with diesel engines are hitched to a heavy trailer and asked to tow a huge load up a steep, 8 mile long hill, they all are within about 30 seconds of each other arriving at the top. Buy the one you like best. I really think they are all good, just with different personalities.

There was a time when Ford and GM used junk diesel engines, but those days have passed IMO.

I feel like my 2015 Cummins acts like it's a little more relaxed when towing compared to my brother in law's 2015 or 2017/8 Powerstroke. The Ford feels quicker empty, but it seems like the trailer taxes it a little harder towing. They're both extremely good tow vehicles, obviously. I haven't towed in a recent model Duramax so I can't compare it. I think we've all seen enough objective testing to know that the three of them are all plenty good from a towing performance standpoint, and then personal preference will come into play.

I will say that up to recently I would definitely take the Cummins over either the Duramax or Powerstroke. If you're talking 2019+ models, I think I'd opt for the Duramax since the Cummins went to the CP4 pump.
