What a difference in reputation between a so-called "trailer park" and an "RV campground!" Some of the latter, although, thank goodness, not too many, have rules that the RV must be motorized (i.e., NOT a trailer) and must be less than 10 years old. My husband and I own an RV and plan to travel around the country in retirement. I can't imagine staying at the really snobby places.
BTW, I can verify that some of the stereotypes about RV'ers (whether trailer owners or owners of motor homes) are indeed true, based on my experience. They are overwhelmingly white, the Americans seem to be quite conservative politically (I don't know about the Canadians because I don't know what issues divide left from right in Canada -- other than it isn't health care), they tend to be religious Christians who attend "nondenominational" services that the campgrounds often hold on Sundays, and they're often friendly people on a personal level.
