So to continue beating the dead horse, I have a 2022 Ram 3500 Laramie crew cab long bed diesel dually. Here are the specs.
GVWR - 14,000#
GAWR Front - 6000#
GAWR Rear - 9750#
From the door sticker "The combined weight of occupants and cargo should never exceed 5569#"
From the truck camper document "Cargo weight rating (pounds) 4738"
So this guy said the weight of the camper loaded was 6500#. No matter which cargo number you use from my truck, which is very similar to his truck, the guy was at least 1000# overweight, and close to 2000# overweight from the truck camper document. Not sure how his argument could ever stand up.
