louise, my x's parents both took early retirements at age 55, sold their home, gave away their furniture, and became full-time Airstreamers for over 15 years. They traveled all over the US and Canada and absolutely loved every mile!
Also, 26 years ago my x and I decided to forsake the city life and the fast lane to make a move to the mountains of NC. Our kids at the time were 13 and 11 so it was do it now or regret not doing it for the rest of our lives. We made the right choice, they have both married wonderful people and their lives have been blessed.
So my 2 cents worth is....go for it and have a blast doing it!
