Nothing wrong with your thinking at all. I'd suggest either renting your house out for a year, or have someone look out for it in your absence. Put your stuff in storage or not. It may be expensive to hang on to it for a year, but I think you will know within 6 month to a year if you REALLY want to give it all up. We did it in 3 months or less, but everyone is different, and not everyone can cope with being separated from belongings and kids/grandkids. It's your choice.
However, having said all that, the freedom of no more house, and all that it entails, being in a different location any time you choose, being able to spend a few days or a few months in a particular place that you like, is like nothing else you will have ever experienced. Since you are asking whether or not it's a crazy idea, only you can decide, but if it is, there are many, many of us right here on this forum with the same crazy idea. We full-timed for 10 years, until minor health problems and age, made us build a house. But, we had ten wonderful years to find out where we wanted to spend the rest of our days, and are totally happy with the decision. We are happy to be in a place WE chose to be in and not forced upon us by circumstances. We have been to all the the states except Hawaii, and they haven't yet built the bridge. Our kids are scattered, but most of them 2,000 miles away. We miss them, of course, but we visit them often either by phone, e-mails, or in person. (They really do have to grow up on their own sometime in their lives.... <G> )
We especially love being on the road and meeting people from all walks of life, from retired plumbers to multi-millionairs. It is a totally different mindset, and one that really sets you apart from family and friends once you try it. You will have so many interesting experiences to tell about and remember for a very long time. And this forum is a great place to start. It is where we cut our baby teeth. We never camped. Bought a really old RV on a whim. Drove it out west and had lots of trials and tribulations, but it only made us want more of it. In less than two years we contracted to sell our 9 room 14 acre farm with a fabulous view, so that we could park our RV in places with even more spectacular views. We met some wonderful people right here on the forum that have continued to be our friends, and continue to meet more each year as we meet at rallies around the countryside. Just give it a try. You won't know what you're missing until you do. Daisy
