Isn't that a common issue brought up by owners of 3/4 ton and up trucks... that the half tons might be able to make it move, but they can't stop the weight? Seems to me that this test will show just how long it takes to stop these rigs.

I bet that an F150 towing 11,000 lbs can probably stop that weight in a shorter distance than a Ram 3500 towing 30,000 lbs can stop. Yet somehow it is considered "safe" to pull 30,000 lbs with the Ram (within its ratings) but it is out of control to pull 11,000 lbs with the Ford (within its ratings).

I'm not sure that I follow the logic that a Ram stopping from 65 mph in 500 feet is "safer" than a F150 stopping from 65 mph in 400 feet. I'm making these numbers up, because I don't know the exact numbers... but you get my point.
