2020 GM 2500HD Dead Weight Hitch Tongue only 500 lbs ?

That VIN decoder webpage really isn't vehicle specific even though you put in your VIN number. Many of the specs provided on that webpage show the same for all GM trucks. For instance, I have a 2020 2500HD Duramax Crew Cab standard box. When I use the decoder webpage with my VIN number it shows the same 500 pound rating but on the actual sticker it gives the vehicle specific numbers. This sticker is from my truck.
