Used to load my brothers 69 C10 with 8k in the bed far too many times enough that the coil overloads had buckled the frame where they sat, the axle housing was also dented where they say.......
Poor little single horse trailer with the box torn off had 3950lbs of scrap steel in it awhile back... My ranger wanted to die on that trip.
As far as certifying it I'm not sure on that one.. As long as you don't have a business name on the door and a DOT number along with it you would likely never have an issue with a scale.
My dads '01 3500 4x CTD is licensed at 16k with only the addition of air bags and they never inspected it...
