We have spent hundreds of night at Walmart truck stops any place there is a shopping center with overhead lights in the parking lot. We find the farthest light away from the building and park and within hours there's five or six other campers and trucks surrounding us for security. Being ex law enforcement every state has a castle doctrine which is that you have the right to protect your home. When you're camping your camper is your home. I carry a double barrel shotgun have never had to use it but it always is there in case. When we stop at Walmart we usually go in and buy 40 to $60 worth of stuff so it's more expensive than camping at a campground. If Walmart does not want you to camp there they're just playing losing money.
