WD Hitch effect on TW ratio
Lets run an example using easy #'s. My trailer weights 1000lbs My hitch weight is 100 lbs, or 10% of the overall trailer weight. I put my trailer on a weight carrying hitch, 100lbs is carried by ...

Maybe explaining the reason I ask will help everyone understand why I want to know.
Lets imagine you have a TT that has 12% of its weight on the hitch, and when you put that weight on your TV the trailer tracks right behind the truck straight and great. Only problem is... putting all that weight right on your rear axle creates a situation where you are over your axle rating. So you go get a WDH, move some of that weight to the front axle AND some of it to the rear axle of the TRAILER.
Do you no longer have 12% and straight and great due to the added load on the rear axles and the weight moved from the tongue?
The thing that confuses me is that people say WDH does not reduce the weight of the tongue, it simply relocates the places that weight travels to the ground. That makes sense.
I am confused about the effects this has on the 12%.
Hopefully my question makes sense?
A couple of points ....
1. TW if defined as what you would measure using something like a Sherline scale does not change.
2. W/O WDH the TW will increase the weight on the TV rear axle more than just the TW due to some of the front axle wt. being redistributed to the rear axle of the TV so a 1000lb TW might increase the rear axle TV wt. by 1100 to 1200.
3. With WDH the increase in wt. on the rear axle will become less with some redistributed to the front axle of the TV and some to the TT axle(s).
4. This is subject to debate, but some simply add the wt of the WDH system to the Cargo, but I think and believe it counts as TW with respect to the receiver TW rating. That is to say for a 1K TW receiver and a 100lb WDH system you can only have 900lb of TW as you would see on a Sherline scale until you reach the 1K TW limit on the TV receiver.
