If you think its bad here you should see the sticker-reading weight police in the Truck Campers section!
When a 2500 and a 3500 have the same axles and same frame, they have the same abilities. You can quote artificial sticker numbers until you're blue.
I've read about guys spending LOTS of money trading in for new trucks just so they are within those sticker numbers, because they think they are unsafe and illegal... but now with a new truck that uses the same actual parts, they feel safe.
Or they'll buy the gas truck because the stickers say it has a higher payload, since the engine weighs less.
Drives me nuts. I have to keep reminding myself it's their money and their truck, who cares.
