Maybe we should all get back to the original question, which was "best weight distribution hitch". Honestly, they all distribute the weight away from the the hitch just about the same.
Hitches like the Hensley and Propride, etc. might have more robust sway control built in, but they sacrifice other features to get there, like cost and flexibility. I'm pretty certain that they would be extremely difficult to hitch and unhitch at some of the places I camp. Besides, their superior sway control has been completely unnecessary to what the Equal-I-zer provides in a much simpler package.
