Yes it is true where 100% of the torque is going into the receiver, however it is not always being reflected at the front wheels of the TV. It is being lost in the process.---

Well, I thought we were in agreement. Now, I'm not sure. Perhaps it's just the words we're using to try to explain our thoughts.

First, I think we can agree the WD bars cannot generate torque as long as there is "slack" in the bar/hitch/drawbar/receiver/frame system.
So, I suggest we focus on a system from which the "slack" has been eliminated.

IOW, if the bars are generating torque, there is no "slack" in the system.
This means 100% of the applied torque is transmitted to the TV and the loads on the front and rear axles will change in response to the applied torque.
For example, if you apply a torque of 4000 lb-ft (CCW when viewed from driver's side) to a TV which has a 12.5' wheelbase, 320# will be added to the front axle and 320# will be removed from the rear.

Laws of physics demand that the torque and force applied to the TV (in this simplified example, the applied force is zero) are exactly balanced by reactions at the axles.
IOW, 100% of the applied torque and force MUST be "reflected" in the axle reactions.
Neither torque nor force can be "lost in the process".

When some folks talk about "consumed" or "eaten up" by the receiver, “I believe” they are referring to lost motion or excessive rotation in the receiver system.---

If that's the case, they also should refer to the differing amount of WD bar force resulting from excessive rotation rather than stating that the same amount of WD spring force does not transfer as much load.

Semantics, again, guys....I think violently agreeing in principle, but the verbiage
is getting in the way...

My verbiage is from a few years ago and IIRC when John still had that Suburban
and was measuring the 'deflection' or whatever you guys wish to a call it, on his
receiver (GMT800)

Got tons of PMs asking for explanations. There were a few other threads smack on
that same topic...GMT800 receivers bending upwards (gone beyond their elastic
and into the plastic range of the material/design). There are pictures
of members GMT800 receiver pin box bent upwards, statically without WD
loading

I too can and do 'engineer speak', but not much here. Or try not to as the general
audience is NOT technical and ranges from a smidgin of techie speak
to PE's

I'll dig up some of those threads and link them on this thread, as it is time
and I think germane to this thread....Andersen WD Hitch System and how it works
on various OEM TV's receivers.

Via SmartPhone...excuse my fat finger typos
