So, as a result, how does the rear axle load compare, without trailer and with trailer plus WD? If it hasn't changed - as suggested by the rear height being unchanged - then the rear axle isn't carrying any of the added load.

Maybe if the distance from the underside of the hitch receiver to the the ground increased with the use of WDH, you theory would be correct?
It's a weight DISTRIBUTION hitch, so I don't think the fact that ride height is maintained is an indication that nothing is occurring.

So, I am hooked on the third chain link, leaving two hanging.
Yep - exactly like that. And I agree that that does not necessarily mean that the rear axle isn't carrying more weight.

No, the rear rising (versus unhitched) would mean you are actually lifting the back of the vehicle with the trailer - obviously a bad thing, and hopefully nobody does that.

It's a spring-loaded prybar. If the rear suspension (one without air springs) is no more compressed than without the trailer, it has no more load on it (whatever the source) than without the trailer. Springs - they're pretty straightforward.

Okay, it's Sunday, so my brain is moving slowly...
The receiver, of course, is further back than the rear axle. If the hitch is at the same height as without the trailer, the only way for the rear axle to be taking any of the added load is for the tug to be tilted more nose-down... which unfortunately means that the front suspension/axle is taking over twice as much additional load as the rear. There is no vehicle for which that is even close to appropriate.

If the rear suspension is no more compressed than without the trailer, and it doesn't have air springs that have been pumped up, how is it carrying more load ("weight")? All springs have the same characteristic: they apply more force with more stroke; if they are at the same position, they are applying the same force.

As I noted above, the rear axle and hitch locations are not the same, so no change in the hitch height doesn't necessarily mean no change in axle load... which is why the instructions for WD adjustment generally refer to checking ride height at the axle locations.

Well, since both Baglo and mine were installed by Reace himself and since both of us experience very good safe towing experiences with our setups, I trust that Reace knows what he is doing and that his setup process has worked as it should.
