We've been on the road since the first of June and so far have visited 8 states and stayed in 14 RV parks which seem to be near 100% occupancy daily. In the dozen or so years we've wandered around the country in the summers, we've never seen the volume of RV'ers that we have this year.
I think a lockdown year and inability to travel abroad has changed peoples idea of vacation travel and visiting new places while still living in your own home has become much more popular.
