And for Harvey: we used to do some "stealth camping" long before I had ever seen a Wal-Mart. I built a van interior back in the day (in the 70s) that gave us a bed, storage, and a 5 gallon water system. It was quite a step up from the motorcycle camping or tent camping we had been doing. The first time we stayed in a commercial campground with that set-up, I overheard the couple next to us in a travel trailer say, "Did you see those kids next door? They're staying in that van!" We laughed - we were living large! I had run an extension cord in to the van... Joan could run a hair dryer and I had a radio with a TV band so we could listen to TV shows. We could (and did) stay anywhere in that.
I don't consider those days as "RVing" any more than making a raft and floating on the river was "boating." The concern I have with Wal-Mart camping is the fact that many people think it is "their right" to stay in the lot. They "set up camp"... get out the grill, put out the awning, and to the non-RVing public, look like "squatters." Not good for Wal-Mart, not good for any local campgrounds, and puts RVers in a bad light. Get a few people complaining (especially if any liquid goes on the ground - many people immediately think: "SEWER!!"), and there will be a city ordinance prohibiting that. We saw exactly that in Rapid City and Spearfish, South Dakota, because some people abused the convenience that Wal-Mart provided.
It got stupid at one point, with city hearings about camping at Wal-Mart. Citizens testified that it was an eye-sore, and they concerned about "the unsavory people" this attracted. Accusations of sewage being dumped in the parking lot (no facts supporting that, but all some people need is to hear that). RV associations encouraged RVers to boycott Rapid City (the main population base in the Black Hills), and the City Council refused to give Wal-Mart the building permits necessary to build a new, larger store until they agreed to NOT allow RV parking.
It was about that time that Good Sam, Family Motorcoach Association, and other RV groups got together to form a "Code of Conduct" for staying at Wal-Mart and other non-paid parking areas. Here's one of the many links about this...

It would be a shame for overnighting in Wal-Mart or other areas to completely go away (ever notice the "height bar" at some lots to prevent oversize vehicles from coming in at any entrance other than the direct path to the loading docks?) because some people treated it as their right to stay.
