I thought the same thing... Good reason to order a truck. That’s probably not even that guy’s truck. It would most likely have a full tank if it was purchased.

Most likely a test drive. I test drove one but I just couldn't do that to someone else's new truck. I got on it to see how she performed but nothing like that.

Very impressive, that thing moved out pretty good. If he didn’t buy the truck, he may have done its first owner a favor. Over the years I’ve seen a lot of oil burning complaints from people who have babied their new engines.

Roughly about the same unloaded 0-60 as the F250 (timed with my Iphone from the videos).
The real difference will be under load. The slightly greater torque of the 7.3L combined with the 4 more choices is forward gears will keep the 7.3L ahead in most conditions of max loading; will stay at peak torque more often.

I agree but a lot of my driving is unloaded and this gives you some idea how it compares to other engine / truck combos.

While this is not a timed proper run, let's keep in mind some Ford vids are Tremors with heavy rubber, and this GM has the little shipping tires. F250 has steel toe boots, gm has puma's. 
Good thing is we got what @ 3 days untill driving impressions are free to publish.
While I dont drive a truck to race at stoplights, 95% of the time w trucks there is a correlation to pulling force too. And rarely does a slow empty truck outperform others when pulling a big load. Older diesel vs gas yes, but not apples to apples.

Assuming the trucks weight is the same, you increase force with more power from the engine, and mass is increased by adding a trailer. The faster truck unloaded will always be the faster truck with a trailer… You can't have something be slower empty and faster with weight behind. Like most of us, you probably don't drag it race yours empty… But unloaded tests can provide a useful comparison of which will handle the weight of the trailer better.

Acceleration is dead simple. Acceleration = Force/Mass.

One example of that being correct is the older cummins. (were slow but tow strong). In every other case I can think of if they excelled in one they did the other. Might make a case where gm older 5.3L were better at 0-60 vs 5.4 better towing. (I'd argue 5.3 would tow as much just at a uncomfortable v high rpm.)
But in any truck offering today if its quick 0-60 vs competitor it "also happens" to pull stronger towing. Could be exception between new gm ram baby diesels as no direct shootout yet.

But it all depends on what somebody expects from their towing experience. Some folks love chugging down the road at low RPMs, and become dissatisfied with anything but the diesel options. A lot of people are bothered by frequent shifting, which is affected by transmission programming far more than anything happening in front of it. A lot of us don't mind high RPMs, but want the ability to get up the entrance ramp and merge at a safe speed, so peak power matters more than other factors. There's a lot to it, and those of us not bothered by high RPMs can get a good relative comparison with unloaded acceleration test.
