Get the app RVPARKY on your phone. Type in your location or the location your going. It will bring up a map showing all the Walmart's, Cracker Barrel's, and even campgrounds near your route. You tap on a Walmart icon and a window will pop up telling you if they allow overnight parking...along with reviews. We actually use Walmart somewhat often as our High School son wrestles, and we are travelling all over for tournaments. Makes it easy to get out of work friday, drive a few hours, crash for the night, and go to the tourney all day Saturday. In these situations a campground would be a waste of money. Good Luck!
