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?
Tom,
The center of gravity of the WD hitch itself will be approximately under the ball. Therefore, the weight of the hitch simply can be added to the tongue weight when determining how much additional load is leveraged onto the TV's rear axle and removed from the front axle. For your example, the weight of the hitch would add 150# to the rear axle and remove 50# from the front.
In your example, the load on the receiver before WD would be 900# plus 100# for the hitch for a total of 1000#. This would be reduced to 700# when the WD bars are loaded to 2000#. The change in axle loads due to the WD hitch would remain the same.
