The weght number for the camper by itself, was he given ship weight of camper, gross weight of camper, And had he ever put it on a "cat" scale to see what in fact what it actually weighed? Not only that but to see how much weight was on each axle of the truck in question. There are a lot of people that tow! A vast majority of them do not understand weight ratings for the tow unit, the towing unit, and how to place the weight in/on the tow unit. Ever see a video of a vehicle towing something a after a bit that trailer starts waving at everyone behind the operator. Usually that occurs if the weights were even correct, BUT where the weight actually was on the trailer (was to far to the rear of that trailer). That is why ( if any of ya drive semi) once we were loaded you went to the truck stop and weighed it on a scale. The official term is called Bridge weight, to make sure that you are not only over weight, BUT also that no one axle is overloaded! At the "BUD" facilities you were weighted before you were loaded AND BEFORE you left their grounds. It had to be correct or it was corrected. NO CORRECT paperwork you did not leave! This protected "BUD" also. as a quick stab of the brakes could shift the load. That's on the driver not the loader. More to towing than dragging something down the road! PS; CAT is a trusted maker of scales. Popular at "truck stops". When I loaded the 66 on the steel deck for the first time. Weighed it and mark the trailer where it goes to get it correct. Each and every time.
