Not retired yet but soon. Currently RV trips are limited to weekends and vacations. Fortunately I live in Az. For short weekends 3 lakes are within 45 minutes. A little longer are into the mountains and some of the most amazing wilderness camping anywhere. Includes the mountain lakes.
For fun I take the Rhino for trail riding and the 12 ft fishing boat for fishing. Some times just some reading or sitting by the fire with the dogs. At times some target shooting with the 22's. Only affordable rounds these days.
Never seem to get bored.
