Serious Camping at WM

There is a Walmart about 5 miles from the park we are currently staying at so I stopped by there yesterday for a Rebox. As I parked I noticed a nice and large Cameo all setup, slides out and left all alone. Figured the owner was getting work done at their auto service area but was still surprised to see the rig in full camping mode in the parking lot. This evening as I returned the movie that same rig is there with full camping gear out including one of those big framed generators. The owners even had a blue poop tote hooked to the sewage line. I have seen people overnight at WM but never setup a long term camp before.

It will be interesting to see how long they stay. Have you ever spotted this type of behavior before? Seems like it is taking advantage of a good thing.
