Saying GVWR is determined by subtracting base weight from GVWR is ignorant at best. As I said, that is a derivative understanding.
GVWR is determined by payload capacity. Let me say that again, GVWR comes from payload. It's not the other way around. Saying payload is determined by GVWR is like saying axles are rated by GVWR/2, it's simply not true, and it's stupid to even think that. I tried to give you guys hints to figure it out yourselves, but I guess you can lead a horse to water, but you can't make him drink.
To determine GVWR manufacturers take axle and tire load ratings, they then determine payload values based on those in certain configurations. Specifically they are looking at worst case scenarios. Once they have that payload value they determine GVWR. I don't understand what other way you could have possibly thought this was done.
So,
like I said payload is determined using GAWRs and/or tire loading. Yes, payload ends up being GVWR-base weight, but that's only because GVWR is determined by payload.
Thinking payload comes from GVWR is derivative, and that's fine if you don't question payload. But, you decided payload "wasn't a thing" without any real knowledge or understanding of how any of these things work. And you were wrong.
I don't expect you to understand this in the slightest to be honest. I know it's going to be wayyyy over your head. But suffice to say, literally every single thing I have told you is a fact, plain and simple. You're wasting my time at this point though. I know you either can't or wont understand any of this, the only reason I'm bothering is so other people who are more open to learning can enrich themselves.
This wasn't even the point of my post anyways by the way, that was that payload
is official and on the sticker. We have already demonstrated you're 100% wrong on that, so I guess you wanted to jump back in on the not terribly relevant part in yet another chance to sound right, but, you should have stopped digging your hole, but you just can't help yourself.
Good day sir /sarcasm
