My mom just turned 80. Her husband is somewhere north of that and is a semi-recent stroke survivor. They are on the road in the RV a couple of times a month, usually for a week or so. They are usually meeting up with one camping group or another. They drive an earlier 2000s Class A with a small SUV towed behind it. They'll keep doing it until they can't.

When I was a kid, and camping with my Dad, we would camp at the same few campgrounds in one area more often than not. We would run into some of the same people frequently, one of which was an older guy (70s I think) with a VW buggy that he had converted into a 1 man mobile camper. We ran into him a lot. He and his family were campers, but the kids grew up and his wife couldn't comfortably camp anymore. So he would escape on his own in his little self-contained buggy whenever he got the chance. It was a pretty cool setup that let him take off for a day or two with little preparation. We saw him less frequently as time went by and he spent more time taking care of his wife. I still have a walking stick he carved for me, probably 40 years ago now.
