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...

Also, there is tremendous potential for banging the ball inside the coupler
Tension the bushing/nut/chains will pull the bottom of that hitch ball shank towards
the TT. The top or the TT's tongue will move forward to contact the pawl against
the ball.
That then creates the WD leverage to lift the tail of the TV and move weight forward.
Once moving, dynamic, the acceleration of the TV will pull the ball forward...reducing the
amount of WD tension, therefore reduce the amount of WD
Slow down and the TT will move forward to increase the WD tension
If you have the brake controller initiate the TT's brake before the TV (leading)
this is just like acceleration where the WD tension is reduced
This goes on and on during any trip. The harder you nail the throttle and/or
nail the trailer brakes, the harder the ball bangs
This will work the coupler and the pawl. What happens over time?
Then the friction material and the taper of the ball shank will also get worked
Since not held in with a nut and the normal approx 500 ft/lbs, how much is there
via that clevis pin? I'd assume next to nothing, as that first video shows it
just drop off when the tension and pin is removed.
The only sway control is the friction material. On a traditional WD with cams
will have both the increase in WD forces and resistance to that side to side
by both the pull and compression of the cam on the bar end.
Another assumption is that there might be a custom couple like SoCal said. But
then that thing must be almost zero tolerance to avoid the above...then it should
be greased...but they said no grease ???
Again...just conjecture till a cross section diagram and/or an exploded
assembly diagram. Also need the tolerances for the ball/coupler union
