It's your country, your motorhome, and your common sense. If Walmart welcomes you to their parking lot, go for it! I would,.... and I do. I'm a member of FMCA and ESCAPEES, and they offer guidelines for overnighting at Walmart. That's fine, but I use Walmarts' instructions, and my own common sense. I've never had a problem while overnighting at a Walmart.
