Thanks Mike and Don.
I looked up the “No Overnight Parking at Walmart” for Colorado and Frisco does allow for overnight parking depending on the weather. They told me the issue was when it snows their parking lot is one of the first the county plows and they need the RVs out early.
I was in Avon Colorado Walmart a couple of days ago and saw a huge Class A RV in the center taking up a bunch of parking spots. His jacks weren’t down but his slides were out and satellite dish was up. It wasn’t busy so I guess it was okay.
