Help with hitch / tongue weight

I think the whole point here is to understand that adding "temporary cargo wt" after the WD is adjusted does not increase the vertical downward load on the hitch/receiver -- it decreases it.

There is no "

extra cargo wt. that constructively appears at the ball/coupler position.

"
The effect of "extra cargo wt." is to reduce the vertical downward load at the hitch/receiver position.

When force is applied to the WD bars as part of the set up process, the result is a reduction in vertical downward force on the hitch/ receiver.
When MORE force is applied to the WD bars by adding "extra cargo wt." and causing the ball to drop, the result is MORE reduction in vertical downward force on the hitch/receiver.

The vertical downward force on the ball mount is the greatest (and is equal to the TT's loaded "tongue weight") when no WD is applied.
When WD is applied, the vertical downward force is reduced by an amount equal to the amount of load which was transferred to the TT's axles.
When "extra cargo wt." is subsequently added, more load is transferred to the TT's axles and the vertical downward force on the ball mount is further reduced.

If the tongue weight ratings of the hitch and receiver are not exceeded by the TT's loaded TW, they will not be exceeded when WD is applied and they will not be exceeded when "extra cargo wt." is added.
