2021 Ram 3500 H.O.

You don't know much about engines and it shows. If you honestly expect to get the same rated power that you would at sea level at 10k feet above see level then you probably need to go read some more on how engines work. Specifically the part where every 1,000 ft above sea level robs about 3% of the power from N/A engines and between .5-1.5% on turbocharged engines depending on how efficient the turbo is at that altitude. Turbocharged engines may no loose as much power as N/A engines do at altitude, but they still do loose some power.

And as I said in the thread specifically about those runs several moths ago, I bet those times would be way different at 80F instead of 30F which I am guessing that the temp was since it is snowing and it has to be at least 32F to snow. I have now doubts one would pull more power to keep the temps in check than the other.
