If anybody cares --
The techie stuff and calculations that I removed from the original post go like this.
Assume that my total trailer weight is 3800 pounds
. . This is the dry weight of the trailer, plus the factory options and any aftermarket options, plus all the stuff I packed onto it.
Assume that a TM puts 14% of its gross weight on the hitch = 532 pounds
. . This is more than the standard 10% recommended by trailer experts. It came from the TM factory in Tennessee.
. . This is what makes a TM so sway-resistant.
The TM axle weight without a WDH would have been = 3800 - 532 = 3268
The TM axle weight with the WDH (measured) = 3360
Therefore the WDH shifted 3360-3268 = 92 pounds from the hitch ball to the TM axle, and took this weight off the tow vehicle's rear axle.
. . It also shifted a similar amount of weight from the hitch ball to the tow vehicle's front axle.
. . Taking weight OFF the rear axle, and adding it TO the front axle is what levels the tow vehicle.
Obviously I didn't have the WDH cranked up very high. It would have been interesting if I had cranked the hitch up one more link, and then weighed again. But I didn't.
This illustrates how the WDH moves weight from the tow vehicle rear axle to back onto the TM axle.
