Gotta chime in here...Where does tongue weight end up with a wdh?


I observed back of tv dropping way down if I just drop tt on to hitch = full tongue wt.
Use of wdh levels out tv and also transfers weight ..Right? therefore you are not putting all of actual tongue wt on tv.
Or am I missing something here?

The WDH actually transfers weight that is located over the TV'a rear axle ..., the weight will be transferred to the TV's front suspension and some weight to the TT axles. Ideally, one wants to return the same weight (via WDH) that was removed from the TV's front suspension when the TT tongue weight was initially placed on the TV's hitch ball. The nominal weight transferred to the TT's axles is just a by-product of the WDH meeting the TV's front suspension requirements.

The effect of the TT tongue weight being placed on the hitch ball adds weight to the TV's rear axle and at the same time removes weight from the TV's front suspension. The TT's actual tongue weight on the hitch ball for the most part remains a constant.

A visit to a CAT scale is a good place to see first hand how a WDH can distribute weight, where, and how much.

Yes, the tongue weight is on the TV. My way of visualizing it:

Imagine the TT frame welded directly to the TV frame. All of the weight forward of the TT axle(s) - the tongue weight - would be on the TV frame. Without a ball, there would little rear end sag of the TV because of the lack of a pivot point and the TT would be level.

Now imagine there is a hitch ball, but no WD bars. The rear of the TV wants to drop down due to the tongue weight, but when you see that, you put a steel bar between the TV tailgate and the propane tanks (No, please do not try it!). Now the TV and TT stay level.

WD bars pivot from side-to-side to allow cornering and allow the TV and TT to go over vertical changes in the road, but perform much the same weight transfer that a solid bar would.

In some forum (maybe not in JOF), there is at least one very detailed force analysis of the weight transfer using a WD hitch.

(I see there are new posts on this topic, but I'm going to post this before I read them.)

After giving further thought to my post (oh no thinking again lol) I more or less came to same conclusion.
Then you guys really nailed it!
Thanks
