The only reality of those TFL videos is the armchair racing and brand loyalty comments that follow. I live about 45 minutes from Eisenhower Pass (the real name, not IKE Gauntlet nonsense... OP, not criticizing you :)) and those videos are about as valuable as Toyota's Space Shuttle advertising stunt.
It is amazing how many, who watch those videos, take to heart that because one truck made it up to the pass 30 seconds quicker, the other slower truck(s) are complete junk. Are people really that stupid?
Those who drive that stretch of highway also know that it is not often you can wide open throttle it all the way to the pass because of traffic. Also not shown, adverse weather, wild life dodging, blinding sun rises/sets etc.
The most important thing you should be looking for in a truck is can your choice of truck tow your intended weight safely at an adequate speed to get you to your destination.
