My thought is this: That truck had 4wd and the Gov-Lok, which locks in at least three of the four wheels. Lets say bone stock, but if it has a cheap tuner, installed, even better. Guy backs in, hooks up, and pulls forward easy unitl the weight of the boat is on the trailer, and then stops. He then punches it (from a stand still) and shifts the gear shift into "1" in that order. Tow / haul in or out, does not matter in my experience. Torque management limits the amount of power. The driver probably punched it, didn't go anywhere, and never looked at the tach. Probably didn't get past 3000 rpms. This happend on my 2004 on weird occasions, but if the wheels had any momentum, even the slightest roll, TM was never an issue. Only from a dead stop. Tow/haul seemed to have no effect. 2004 and 2005 were the first years of the drive-by-wire and TM and there was all kinds of complaints about them. Most were fixed by a simple software re-flash.
FWIW I agree on the torque management thing being a problem in the early 6.0L, I had a 2002 2500 Suburban with the 6.0L and it felt weak getting a trailer rolling. Until I had an aftermaket tune done, which removed the torque management. Before the tune I felt like my '05 5.3L 3.42 geared work truck did a better job of getting the torque to the ground.
