Some think that sticker on the door jam is a commandment from god, or at least a gov mandate. I once bought a few tractors that had a GVWR of 32,000 or less, (don't remember for sure, know it was 12 steer, 20 on single drive), and a GCVWR of 80,000. I did a lot of changing to make them do what I needed to do. Basically I used the engines and cabs. About a week after I put them to work driver got stopped for torn mudflap. LEO, matching VIN to paperwork saw that 80, looked at BOL, that showed GCVW of 110,000. Now normally my drivers would pay 30% of fine, but I needed them moving rock, so I told them it was all on me. By the time I went to court on the first one I had over 40 tickets in hand. Cost me a little with the lawyer, but the judge explained to that officer that the only number on that plate that was any of his business was the VIN
Now I was dealing with CMVs. But most LEOs are more likely to be strict with CMV, but not look at RVs
Now I'm not saying running over your ratings is a good idea, because it will cause handling issues, and wear parts faster.
