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...

Maybe this will help...a bit...
WD springs (round bar, trunnion and now Andersen plastic bushings) all have a
fairly short travel with the plastic bushings the shortest
Most receiver pin boxes are mounted (welded, etc) onto the receiver cross tube.
Some tubes are square, others round. Some are straight, others bent to go around
stuff. Some even have a 1/2" or so thick plate bent around exhaust pipes.
Most are then welded/bolted to the end brackets, which then connect to the TV frame
Most all cross tubes are in torsional tension, which is really a torque tube
In working, that cross tube twists till it reaches a limit of 'twist' or travel
that will then transmit that force to the end brackets, then to the
TV frame
Going past the elastic point will have the cross tube and/or the pin
box assembly 'stay' bent. The design criteria is to have it twist
and not go into and past the plastic point. Goal is to have it stay in
the elastic range where it will snap back
The amount the GM GMT800 receiver's cross tube *AND* pin box assembly 'twists'
is much LARGER than a traditional receiver pin box assembly and cross tube does
It goes past the elastic point and into the plastic range easily since
the design is not stout enough. There are production issues too and
has to do with the poor welds. There are also design issues, but that
is discussed in other threads.
Since the WD Springs only have a limited travel, if the receiver assembly requires
more travel than the WD Hitch system can provide...there isn't going to be
'enough' WD imparted onto the TV...
