I have said for years how to conduct the test using cruise control and lowering the desired speed to hold the desired speed and also locking in the desired gear. The RAM simply used the high RPM's at 35 to their advantage and I will say their programming must have improved since my 2015's tech because it held very nicely without adjusting cruise speed.
Your right, the first step is to think about what gear the transmission needs to be in to hold back the load. Secondly you want to set your desired speed close to redline in that gear. Then at redline the wheel brakes come on. Had they set the speed at 38 mph it wouldn't have applied the wheel brakes till 55 mph. Additionally the rear axle torque that the engine can deliver at max exhaust pressure, which I believe is 60 psi with the Cummins exhaust brake, in 3rd gear is only 67% of what it is in second.
I'm sure if they would have braked enough to get the Ford in 2nd they would have been very impressed with its ability to hold a steady speed.
