Clarification is needed.
Permanent residents = people who 'permanently' 'live' in a permanently parked trailer or mobile home. That does not make them an RV'er.
Seasonal residents = RV'ers who leave their RV in place and visit it seasonally.
Either just weekends or for a full season in the summer/winter months depending on the region.
Almost all CG's have these two types separated within the park. People who RV like to park next to others with their same interests.
Most CG's I have been in they even separate the seasonal section from the CG section also. Because in that CG section people are pulling in and pulling out all the time. That would be a pain to have a seasonal spot and have neighbors on either side pulling in and pulling out all the time.
In answer to the OP. I have found when staying at a CG short term that has a 'seasonal' section. These people have bonded friendships with their surrounding neighbors. And don't very often venture out of their section to chit chat with the RV'er that is parked there short term or long term where they leave with their RV.
I will not stay at CG's that have 'permanent' residents.
