I just mentioned previously, Option B is telling me the WDH isn't set up very well if this example requires air in the bags to level out the TV after the WDH is set.
I understand what you are saying but if you have reached the goal of 500 lbs restored to the front axle, the back is wherever it is. If you distribute more weight to the front to raise the back, you will be transferring additional weight to the front axle exceeding the 500 lb goal. You will get the truck level but you will remove more than the goal amount from the rear axle to accomplish that.
On edit: I screwed up the quote and I don't know how to fix it
"The goal". That's all been made up here and its really pointless to debate and discuss. I want no part of that that because nothing like it ever exists in real life where you have a known weight to transfer with a WDH and that you want to track. It doesn't work that way.
One can measure with a couple passes at truck scale to find out what has been distributed to the trailer and front axle using a WDH, and that discussion ends with actual numbers. Numbers that are nice to know, but you don't "need" to know unless you're checking axle weights in the process.
I understand what you are saying. I am more of a visual person myself. In keeping with the spirit of how this forum functions, explanations are explained in a mathematical format (I just learned that myself). Fictitious numbers have to be used in order to explain how, in this case, a WDH works. Bear in mind that the example refers to a WDH and the fictitious numbers actually refer to percentages of weight so if your weight is actually a little higher or a little lower, the percentage of the weight is transferred the same way. The idea behind a WDH is to distribute the tongue weight across the the axles of the truck and trailer in accordance with guidance (written by engineers) that we accept so that we may obtain a good stable ride. I certainly believe that there is wiggle room within that guidance so that you achieve the ride you are looking to get. The guidance can also change as it recently did.
My issue is that people drive across scales as you suggest to get real numbers when setting up their hitches and they check those numbers against suggested limits and they are right there and think they are good to go. In my experience, like in our houses, we accumulate things as time goes on, so I think that if someone wants to stay under those "numbers", they should not go right up to them on initial setup. If they do not care about those "numbers", then I don't understand why they would bother going over the scale to begin with. Also, if someone sets up their truck right up to the numbers and uses them as a guide for moving items around to be within the "numbers", there is a problem related to fine tuning to obtain a good ride. I think that there is the possibility that someone who sets their truck up and stays under the numbers could have a setup that is not stable and although they think they are doing good, they are not.
