If you have a relatively inexpensive way to get back out on the road for a while I would recommend you give the RV life another whirl. Can you rent your home? Rving just isn't for everyone, and I'm not sure, based on your active life with your friends, that it will be for you.
Now that you know what your fixed incomes are you know exactly what you can and can't afford. That being said, is downsizing and moving into a nicer mobile home park or something like that an option?
