If it were me, I would not give a rats hiney what they door sticker says. In Wa st where I am, all the LEO's care about is how much weight I have paid for. If it is over what I weigh, I am legal, if not, illegal! Also as long as I do not have more than 500 lbs per inch width of tire on a single driveline rig, or 600 lbs for a duallie setup, I am legal. Door sticker be danged! I sold my 05 dullie 2 years ago, it had a 14K registration on it. No issues selling it! New owner kept the 14K plates. I was legal to 14k, not the 11400 on the door sticker.
NOW, if one gets into a civil court issue. That door sticker may mean something. But as I saw recently re a towing article. maybe it was here, buy yourself plenty of insurance, do not worry about door stickers!
