I understand that, and I expect that. However, no matter the configuration I put in, it gives me 4240 lbs payload. I find it hard to believe that every combination of features I have selected add up to the same weight. Trucks built and on dealer lots show the same capacity. Every single one of them. DRW, SRW, short bed, long bed, 5th wheel prep, hitch included, doesn't matter. All the same payload. I can look up used trucks by their VIN and get different values, but new trucks don't work on the look up site apparently.
Problem I have is, what options can I consider and still reach my target payload? The website as it is currently operating is useless for me. I have reached out to a couple dealers, but so far I don't have any feedback on what options can be selected and still be able to put 5200 lbs plus of cargo/people/pin in the truck.
