There are some Retired and other RVers that do stay a night at a Wal Mart or Truck Stops. They have nice RVs but it helps to balance their books. Guess what: they spend money for groceries, etc and even fuel at some, of them.
No way we can address those who have been kicked out of their jobs and homes etc and now use their RV, only thing left, to live. Very unfortunate. Remember the great things free trade has done.
When we stop at a WalMart we usually end up spending several hundred dollars, on supplies, even fuel for coach and towed, at the few we can get in.
I spend an hour or two or three at the coach while she shops. Like at Deming New Mexico. One acceptable campground up the road but don't believe the rates etc. The sign remained unchanged for years.
Didn't know it and were too tired, at that point, so we, with the blessing of security, and directed, to one area, of lot, set up for the night. Unhooked towed and went to find a place to eat. Turned out Border Patrol and Military ate there.Mexican Food was blech and desert simply terrible but they had Mexican Coca Colas, a memorable taste but still half flat.Got the oil changed from were Freighliner,in Tn overfilled our coach by thirty quarts,and ruined our dipstick and it greased the rear of the Mh and probably the road from there through Miss, La, Tx and New Mexico and Az.
There have been several planned stops for supplies and to eat someone else's food ruined when we turned toward a Wal Mart and a big piece of pipe hanging over the entrance, in Jackson, Tn, in La and some others. They didn't get the few hundred dollars we probably would have spent. The Cities didn't get our sales taxes either or fuel sales, or restaurant revenues either. Why would I seek out a run down RV park in these places that thing RVers should be forced to provide them a retirement. That attitude will come through at their Parks as they generally too cheap to hire good people and or run it themselves.They are miserabl people and make others miserable.
