As a past owner of a Hensley hitch and if I ever return to a pull trailer again I will own a ProPride, I just can not understand how you would think that either of these hitches can possibly exert any additional forces to the factory or aftermarket receiver hitch. It isn't even logical. A trailer of any weight swaying at 65MPH exerts MUCH greater forces on the receiver. I'm positive a call to Sean at PP or Hensley would give a clear explanation. But I'm not an engineer, just a guy that knows the benefit of a quality engineered hitch to remove sway. And ProPride does exactly that!
