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.

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.

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?

The Ike is actually not a very steep grade for much of the hill. The average slope of the grade is only 5.6%. The grade starts out about 3.5% for the first 1.5 miles, then increases to about 6% and near the top there is a section that approaches 7%. To tow a 20,000 lb trailer up a 7% grade at 60 mph would take over 500 HP. To climb a 5.6% grade towing a 20,000 lb trailer at 60 mph would take very close to 430 HP. The 2021 Ram with the HO Cummins is probably rated to put out about 400 HP at 2100 rpm. Even though these trucks have turbo charged engines it is unlikely that they put out rated HP at 10,000 ft of elevation. So, they would not all be capable of keeping the speed limit up the Ike with 20k in tow.
