What is meant by "camping alone"?
Does that mean by themselves in an RV no matter where it's parked ... or in an RV with X-number of people in it but parked out in the middle of nowhere?
In either case, finding an RV club to go on outings with would solve any problem one might have under either definition. We even recently joined a club with a purpose not directly related to RV camping at all ... but they do go to excellent remote locations to participate in what the club is about ... many of which just just happen to be great out in the middle of nowhere camping locations. We joined it both for what the club is about and so as to be able to take our RV in interesting remote spots ... but not "be alone" while we're there.
Our main concern when being by ourselves ("alone") in our RV is mechanical reliability of the RV - since we do not tow another vehicle.
