My ex and I full timed for 8 years....work related. We stayed in RV parks in several different states. Sometimes weeks, sometimes months. Even for almost a year at a time....twice. We saw it all. Overnighters, weekenders, short term vacation folks discovering the area, long term folks working jobs of various types, and some permanent residents also. Tried to be friendly, respectful, minded our own business, kept our spot and our rig clean and neat. We also met a lot of fun, nice, friendly, interesting people. I still keep in touch with a few.
I guess we were lucky. Had very few negative experiences.
