Tom,
If I saw a topic with this title, I would assume it pertained to why a tow vehicle is limited to carrying a certain amount. However, from your writeup, I assume you are talking about the contribution of tongue weight, hitch head weight, and weight distribution to load on the TV.
Rather than going through all the percentage calculations, it might suffice to say that, for estimatimg purposes, one can assume that a properly installed WD system can decrease the vertical load on the receiver by an amount equal to 1/3 of the hitch weight. However, one should always measure the actual weights for comparison with the TV and TT ratings.
Thanks Ron,

I did want to make a point of how much (in percentage) a WD hitch relieves the rear axle, hitch, and payload capacity.
I was not going to go through the percentage calculations - just use some of the results.
I am still not sure about the weight of the WD hitch itself - would any of the 100#s be noticed in the rear axle load (after engagement)?
Would the full 100#s be used to reduce the hitch capacity in my example from 300#s to 200#s removed?
I know that a Hensley would be added to the tongue weight, but not sure about an Equal-i-zer or Dual Cam hitch. Seems like they would not become a part of tongue weight, but rather would be primarily supported by the TV hitch.
