Andersen Hitch Failure

I have watched the video from the Anderson people and their test show it performing as a downward pounds of pressure, but a catastrophic panic stop could cause failure in the other direction or a sudden pulling action from the rear causing a sudden and large amount of rearward force could have caused this rearward failure. I have the steel version and I believe am well within the design limits. I try to be constantly aware of what I am doing when ever I get behind the wheel of what ever I drive especially when pulling my trailer, but like so many other factors out there **** happens all the time folks. I drove heavy semis most of my adult live, and there is the case that can be said for metal fatigue from sudden amounts of force on metal that can sometimes cause failure. Case in point the twin towers and metal failure because of fire on the metal supports melting from intense heat and pressure on the structural design.
