There are many kinds of RVers, everything from the Friday and Saturday night at the lake camper who wants to maximize their "camping" experience, the one week off work camper, the traveler whose RV is their motel room on wheels, to the full timer whose RV is their home, and combinations of all the above. And then, throw kids and pets into the mix.
Quiet times are there so that the various RVers can co-exist. We all have to respect the rights of the other RVers, and other types of RVers. None of us can have exactly what we would like in a perfect campground, one area for weekenders, another for travelers, etc.
Lets think of the other RVer so we can all enjoy "camping".
