Thomas,
Please consider this situation.
A toyhauler trailer is overloaded in the rear and ends up having a tongue weight (by your definition) of ZERO before the WD bars are tensioned. The WD hitch (from my example) then is hooked up and applies an upward force of 1000# at the end of each 30" spring bar.
What is the tongue weight before and after the WD bars are tensioned?
How much of the ZERO tongue weight is distributed to the TV and TT axles?
How much has the load on each axle changed as a result of tensioning the WD bars?
On edit: Please assume the toyhauler and TV have the dimensions shown in my orginal post.
