Check out the :20 mark where he has to use both hands, and runs his left arm through the steering wheel in order to move the other shift lever!
I've ridden in a truck with a similar transmission, but never drove one.
Here's probably the fastest tractor trailer I've ever driven. That Tractor was geared to run about 125, though I never got it nearly that fast. It had a "13 Over" which is just a 13 speed where the top half of the 4 speed "H" pattern is split into Direct and Overdrive.

The company I work for now has 90 % of their trucks set to 64 - 65 MPH
