I believe all the mfg rate to a combined vehicle gross weight of 10000# for the 3/4 ton class. Keeps them below a CDL requirement in all states. So my practice has been to hook up and head to the CAT scales. I look for front axle plus rear axle weight to be less than 10000. This helps me account for after market addons (bed cover/liner, sidebar steps, etc) with pin weight, passengers and cargo. If all that is good then I look at rear axle rating. So much confusion about what's in what's out, scale makes it clear. If it changes and we see the max Gross go to something higher than 10000, say 11,200 or such, then do CAT and subtract the TV weight from the 11,200 to get available payload. Of course a negative number means yo are too heavy.
