Wadcutter,
Thank you for your post. You explained it as I understand it. The law is not based on the door sticker of your vehicle. The law is set by the state that you are in or where your registration is from. There is so much BS posted on this forum that you have to look hard to sort the fly dung from the pepper.
If you are over your door sticker weight this might cause the Manf. to try and void your warranty for certain failures that the manf may claim to have caused the failure. Remember that there are laws that state that the Manf must prove that the failure was caused by misuse.
To answer the OP's question more directly I live in MI. and I have traveled through the states you mention I have never seen an RV pulled over to be weighed and have no knowledge of anyone that has been cited. I think if you have any weight concerns that they are probably ones that you should deal with on a personal saftey level and not worry about the laws. Enjoy your trip and be safe.
