This thread reminds me of a commercial I watched a long time ago showing a small car without rear wheels towing a trailer. The picture below is not from the commercial (it’s from eyershitch.com) but shows a couple of vintage cars configured similarly. It’s caption indicates the tongue weight. The magic of a WDH!

Yeah, I've seen those. Keep in mind, they were explaining the whole idea of a WDH, so referencing the hitch weight prior to implementing the WDH was a key aspect for people to understand what it does.
If we want to be pedantic you could list two tongue weights:
- Non-Distributed Tongue Weight (NDTW): The weight on the receiver without a WDH bars connected.
- Distributed Tongue Weight (DTW): The weight on the receiver with the WDH connected.
Note: I said "receiver" not "ball" because as shown previously, a WDH can substantial increase the weight on the "ball" but that can be misleading as the bars negate a large part of what the receiver sees.
So assuming you are towing with a WDH connected, you would want to use the DTW as that's what your truck suspension sees.
