It did way better than I expected going up. LINK

I just watched the video and crunched the numbers. According to my math the 7.3 was producing an average of 344 hp at the crank during that run..... and the throttle would have been backed off for part of the hill to keep from going over 60. Using the same math the 2020 Duramax put out 341 hp towing the 30k lbs up with the throttle pinned the whole time.
