I test drove this one yesterday: 3C63RRNL4MG617369 Detailed specs on ramtrucks.com new inventory search shows Max Payload of 3,990 pounds. Look up my vehicle shows 5,168 pounds. I could not find the sticker on this vehicle--must have been looking in the wrong place, because it should be there. All I found was the axle rating sticker.
Here is the second VIN: 3C63RRNL3MG647253 Detailed specs says 5,520 pounds. Look up my vehicle says 5,340 pounds.
I've compared dozens of VINs now looking for differences in config that might account for the 4K vs. 5K max payload. Only the 4.10 seems to consistently predict the difference on the ramtrucks specs. I'm not sure whether to believe Look up my vehicle, even after the lawsuit.
