This really isn't impressive at all.
Look at the rear suspension of the pickup. It's got a ton (probably literally) of weight in the back. Friction is based of the force being applied to the surface (all other things being equal). No shit a pickup with an enormous load is going to be able to out pull a semi that doesn't have any weight on it's drive wheels.
Note that the semi's wheels are just spinning. It's not getting out pulled. It doesn't have enough weight to generate sufficient friction.
Try it again with several tons on the rear set of axles and I'll be impressed.
Guy in the semi also keeps flooring it making the wheels get no grip when he loses it.

If you want something impressive, watch a turbo diesel land rover take on a 5.6 ram. :v:

I too enjoy a ruined transmission and possible frame damage.

I would love to find a fucking single cab dually like that though, but they're few and far between.

the part at the end where the land rover is just on its brakes and the ram is still spinning its tires is the icing on the cake.

On top of the fact that the gear ratios allow for different types of pulling.

Yeah that's correct because the coefficient of kinetic friction is less than static friction, hence his wheels do not get that much grip on the surface.
Damn, you can see the chassis of the semi truck actually flex. Although I gotta agree, if they had a load on the semi the results would be quite the opposite.

Its hard to say, a pick up like this weight about 6000-7000lbs, with a weight distribution of about 40% behind, plus lets say 1 ton on the bed, it will be about 4600 lbs behind, these semi weight about 15000lbs, with a bit lower weight distribution behind at about 35%, and thats about 5250 lbs behind. Though it would be instant win for semi if the front wheel could also rotate.
