I don't see a dramatic difference in geometry or operation with the Anderson WDH. It appears to use chain tension on an offset to pry down on the stinger instead of tension bars. The sway control is still friction based which REDUCES sway but can't eliminate it entirely.
If you want to see a hitch that really works different and better than the standard WDH designs, look at the Hensley Arrow, Propride, or Pullrite hitches. They totally eliminate sway in a similar manner to a 5th wheel setup.
The Hensley and Propride are 4 bar linkage hitches which effectively move the pivot point of the trailer further forward of the hitch point ( hitch ball), making it impossible to induces front end counter steering from hitch side loads. This hitch works on any properly equipped receiver based tow vehicle. Even a short wheelbase vehicle will tow safely with this system. It is friction free and uses geometry to stop sway. Its an ingenious design....but cost $2500.
The Pullrite accomplishes the same thing (moving the pivot point further forward) by locking the TT coupler to the ball via a slightly different methodology of w/d bar and forces the hitch to pivot at it's pivot point at the end of it's drawbar which is located just behind the tow vehicle differential thus emulating a 5th wheel hitch, but under the tow vehicle rather than in the bed of it... This is the best bumper pull setup available but won't fit on our WK2s. They are rated up to 20k lbs and 2000 on the tongue. The vehicles receiver is not used. The Pullrite was originally designed to allow an Army Jeep to safely tow a heavy Howitzer cannon without swaying. My Excursion tracks straight in high winds and with semi trucks passing. It also allows the trailer to be jackknifed 90 degrees to the tow vehicle without interference...just like a 5th wheel.
