Most people work up to the point where they realize things are changing. Usually they start avoiding driving at night. Then they start taking shorter trips and driving less each day.
We were at one RV park in Georgia and was talking to our 92 year old neighbor. Him and his lovely wife were only 25 miles away from their stick home. He said that they loved this RV park, met lots of new friends, and that they try to get there every few months or so. At the time when we saw them, he said that his son had driven the coach to the RV park for them, but he and his wife were doing all of the set up, etc.
I guess I learned that if you just adjust to your changing conditions, you can enjoy RVing for a long time.
