Well what to make of this. for my Truck a 2016 RAM 2500 CC Laramie Longhorn, 4x4, diesel, A6 68RFE transmission, VIN 3C6UR5GL2GG305209: The yellow tag on the truck door says 1943lbs for payload, Using the owners manual and looking under "payload" they say to go to a web page and check by VIN. When I enter my VIN on this RAM web page it says 2170lbs. If I use the "2016 RAM 2500 trailer towing chart - SAEJ2807 Compliant" .pdf it shows the payload as 2380.... thats over 400lbs difference between the door tag and what RAM's own Towing table .pdf shows. Thats significant IMO. Can anyone advise? Important for 5th wheel loading calculating
