I just switched from a conventional spring bar WDH to the Anderson, because the hitch ball assembly was becoming a difficulty for me to handle. I am on my second trip, and I am really surprised how much better sway control it provides over the conventional anti-sway bar! Eighteen wheedlers going by are no longer a white knuckle experience.
Comments about less weight transfer are probably correct, although I find it adequate for my 7,500 lb TT towing weight. Raising the tongue jack before final tightening DOES make cranking down the chain tightening nuts much easier.
