Most Wal-Marts will allow an RVer to stay overnight in their parking lots. When you are on a long trip and can't find any rest stops or campgrounds along your route, Wal-Mart starts looking pretty good. The important thing to remember when doing this is to do it the right way. So watch this short video, take some notes and then go ahead -- pull over and stay a night. The price is right: Absolutely free!
