We have run into the 10 year rule several times. It has never been a big deal. I ask the campground manager if they are willing to inspect the bus when I arrive with the understanding that I am happy to leave if they decide it doesn't meet their standards. They always have agreed and we have never been turned away. I don't have a problem with this policy. It is the owner's right to put whatever restrictions on their investment that they deem appropriate. I truely believe it is a convenient way for the owner to turn away undesirable rigs. Kind of like a "we reserve the right to refuse service to anyone", but in a more politically correct manner.
