Torque charts are nice but just remember that's at full throttle and maximum boost while consuming maximum fuel. Not something you encounter when towing down the highway.

For me what's more important is the torque the engine can make while towing and making the towing the easiest while making the best fuel economy. This is very difficult to quantify except for the fuel economy performance. In my mind the Power Stroke is the leader in this category for the 2020 models and I suspect will continue to lead for the 2021 models.


It would be interesting to see brake specific fuel consumption maps for the different engines. I think the Powerstroke was the leader for best fuel consumption for the 2020 models which must be about the first time ever... I've never been very impressed with my 6.7 Powerstroke's fuel economy. Maybe the '21 will surprise me. I will be surprised if the changes to the Cummins have much of an effect on fuel economy.

Who really cares if one truck or the other tows up the Ike 12 seconds faster or slower than the other ones. All three are not your grandfather's truck anymore. Buy what turns your crank and enjoy it.



12 seconds isn’t much but I think the 2020 Ram was about a mile behind the 2020 Powerstroke. It might not matter but it kind of put the Powerstroke in a league of its own. I think it would be nice to see the 2021 close the gap a bit.


If we limit speed to the speed limit up the IKE, AND if we tow a more normal even large fifth wheel up the IKE, AND we say for example that would be 20,000 lbs for that large RV load but it’s not the 30,000+ lbs max load on TFLTrucks, I’m 95%positive all the big three diesel trucks make it up the IKE within seconds of each other.

This is a non issue for RVers now except for bragging rights like my truck is more powerful than yours.

The true leader is the one that has the lowest operating expenses and downtime after 3-400k miles....and we all know which one that is! [emoticon]

Happy New Year! [emoticon]


I know exactly which one that is... [emoticon]

Agreed... But at 8.5 years and 204,000 miles and the drivetrain hasn't been touched it been exceptional compared to others. Especially one that's a daily driver.

When the 6.7 PSD was introduced with DEF was better than the 6.7 Cummins that decided not to go with DEF for a couple of years. Then cummins caught up around 2013 but essentially was the same. I think the '15-'19 Cummins was slightly better.

How many want any truck to pull an rv with 3 to 400K miles. Farm truck maybe. Our 05 with 111K miles drives like it is a new 05 truck. towing down the Cabbage hill that most from Wash st have driven I touch the brake 2 times to go to a lower gear. Almost 15K fifth and the 2001 8.1 liter gas was the same. Probably nobody cares but happy is good and happy new years guys if possible. chevman

Happy New Years chevman!

You’re now bursting the bubbles of all the new diesel, “my truck is 22 seconds faster than yours” , nut humpers! LOL

But in fairness, you have a setup that was about as good as it gets for that era and aside from not having the power of a diesel, it, until last year, was the longest running transmission platform on the market, for good reason!

Yes I’ve watched that video. And I think they tested 30,000lbs without looking at it again.

So my point is all of them would end up at the tip at the same time with 20,000 lbs, do you agree?

All I know is my messily 385/865 RAM at 24,500 combined did just fine in the mountains along the West Coast. I like running up hills fast and never felt I did not have enough power to do the job. So seat of the pants RAM's do just fine. I love the full center console bucket seat Laramie, the 8.4 uconnect, nav system etc. The uconnect is head and shoulders ahead of the Ford Sync system in our 2020 Ford Edge ST.
