I think Steve is on the right path here and I could not agree more about the redundancy of providing two stickers with vastly different numbers. The GVWR and the weight listed in the door jamb would be sufficient to use as a guide, they are both hard numbers that police and insurance company’s would recognize. The sticker in the clove is completely subjective and based on a random scenario that could vary by as much as 1000lb’s.
I think the whole reason behind dual stickers is simply to make every effort to CYA against any type of claim that might come up in the event of an accident.
Not that it matters much but I was thinking about old truck momentarily when I suggested crew cabs will hold 6 passengers. I forgot about that center storage box, in most cases 5 people would be the max legal amount.
