I live in a small town east of Little Rock, and Walmart parking lot has lots of rvs and semi trucks parked overnight. My DS says it is because there are security cameras present. Wal Mart welcomes them as they spend dollars inside. DH and I traveled in a small rv up the west coast and loved it. Saw so many beautiful sights. It was, of course, not our primary residence. He wanted to go w an RV full time and I said no. I need a home base. He is gone now and am glad I have a home. A friend tells how her husband had a heart attack and she had to drive their RV down a mountain road. She had not driven it until then. The Rv we had gave us many rewarding opportunities. My advice is weigh your doubts and fears against the benefits. It is nice not to tote luggage into motels every night and know who has slept in the bed the night before.
