New Andersen WD hitch
A fellow camper bud showed me this. It's new and different. Anyone using one? Andersen WD hitches A U-tube video with the factory guy explaining it. You have to get past MR Truck doing his...

First blush is that the brake friction material in the ball/hitch head is
going to be both a maintenance issue and just like friction anti-sway bars. Getting
them wet, oil, wearing out the friction material, etc problems.
The way they do the WD is placing a new force on the coupler and wonder if the
coupler is designed for that kind of loading. Especially the pawl that holds
the coupler to the ball, as that is where the forces gets localized
Traditional cam'ed spring bars (round and trunnion) both hold back the amount
of off angle the trailer can move and increases the amount of spring bar tension
This has none of that and mainly works on the friction between the tappered ball
mount to the complimentary cavity in the hitch head.
As that 1/4" of friction material wears...does the ball shank then need to be
tightened?
What happens to the union of that tappered ball shank and cavity on a
whoopee-do when the tongues goes negative weight ? Is the nut holding
in the tappered ball shank have a spring to account for that situation?
That kind of force for each 'compliant' bushing has it held onto the tongue with
a clamping mechanism. Will it slip? How's about when it gets wet? Or oil gets
on there? That plate at the hitch head end also rotates in tandem with the
tongue...I'd think they would want it fixed to increase pressure on that
compliant bushing to prevent the tongue from swaying
Since the coupler is forced into the ball (that wear and whether the coupler
is designed for that kind of load) will it bang when the trailer brakes are
initiated to pull it the other way? What will that increased force do to the
compliant bushing over time? Will then bang back onto the coupler pawl when
the brakes are let go and throttle given?
Just some first glance thoughts...
