Well, fir balance. I have been at this for only seven years. Most campers I have interacted with are friendly. But, there is a growing number of campers who are not camping.
Many with expensive rigs may have high stress jobs, and are not at the campground to meet or hang out with new people. They actually may be there to get away from people, or may. be working on a project, etc. That does not make them unfriendly, just in a different mindset. Yes I get very annoyed with people who exhibit bad behavior (drunkenness, trashing bathrooms etc.), but that is not limited to camping.
Overall, I have made many long term friends, while camping, and I cannot get enough of it. I am a long term camper, seldom less than a week, ussually a month, or more. I hang out with weekenders, long term campers, seasonals, permanent residents, etc, everybody is welcome at my campsite.
Are there boring days? Yes. But there are at the S & B, as well. Are there trips where there are mostly weekennders with families, not looking to expand their social circle, of course, but this lifestyle is largely what you make it.
The Bible gives good wisdom when it says, if you want friends, show yourself to be friendly.
Read, talk to campers and all types of RVers. Then forge the life you want. It is all out there for the taking.
Like anything you won’t know if you will like it until you try it. Go to RV shows, sit in and experience all kinds of RV’s. It is not a bad idea to rent different one’s and take some short trips to see if you like it.
