Agreed that the trailer axle weights go up, as does the TV front axle and the truck rear axle weight goes down. But the sum of the three axle weights stays the same That means the tongue weight hasn't changed. Now since many scale weights have a 25 or 50lb increment that may cause a slight difference but it is due to scale resolution.
If the tongue weight changes then that force needs to be accounted for in the force on the TV and trailer axles. If the tongue weight goes down, then the sum of the weight on the other axles must go up to account for it.
Now, if the tongue was nose down w/o wd and now level, there could be a slight decrease in tongue weight due to the trailer attitude which would show up in the weight calculations. But it is going to be minor.
Umm..no
The WDH moves some of the tongue weight back onto the trailer axles.
Nose up or down, doesn't impact the weights enough to notice.
