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.

I have the same take on this topic, 100%.

This will fix nothing! As noted there are many other factors that affect towing capacity than a few tests on who can pull a stretch of road faster or brake a couple of feet shorter. Frankly the makers now provide all the information needed to make a good decision if the user will spend a few minutes educating themselves rather than throwing money at a dealer to get the "hottest" new truck. The latter will continue to do the same dumb stuff and make excuses on why the dealer or the RV maker is at fault.

At least that is a start, good for consumers.

I do not see anything in the J2807 spec about tow vehicle GVWR/payload which is the most common RV towing limiting factor. Oh well. We'll know which truck can win a drag race towing the biggest boat!

why does that tundra have a ford badge?
