We love to stay at Wal-Mart when we are traveling cross country. We were full time for almost 10 years and stayed overnight 100's of times at Wal-Mart stores in over 3000 nights of camping. It was always just an overnight stay when we were on a cross country trip which involves lots of driving, many miles in a few days. We also stay occasionally at rest areas, parking areas, vacant lots and have stayed on grocery store lots a few times, museum lots several times. We've also used Cabellas, Camping World, Home Depot, Lowe's and more. If someone has a large lot and we can get onto it, we'll ask to park and stay the night. All these stays were with permission or were in areas where overnight parking was not specifically prohibited.
As Don said above, we try to park so we can put the slides out over a curb rather than projecting into the parking lot. We have a two-slide coach so this allows us to open the living/dining room for meals as well. We need to open the living/dining slide to get to the pantry and table service. Sometimes we can get by without digging into the cabinets but eventually we'll need to get out some food or dishes.
There are occasions when we can not park by a curb. I carry four red cones (Lowe's, Home Depot, hardware stores) and place those along the side of the coach with the open slides. In those cases, I park parallel to a driving lane with the slides opening on the dividing line between parking spaces on the two sides of a row. This is always a distant part of the parking lot that is largely unused.
We also make a practice of parking late in the day (within an hour of sunset or later) and do our best to be gone by the beginning of the busy day at Wal-Mart (about 8:00 a.m.). Frequently we'll be gone shortly after sunrise. That way we are truly staying overnight and no more.
I use an iPhone app which will find Wal-Mart stores for you and it indicates those which are designated no overnight parking with a red pin and those that are ask to park with a blue pin displayed on a map showing your location as well. That app is called ALLSTAYS ONP Wal-Mart. It costs $2.99 and is well worth that price. If you want something more useful, ALLSTAYS Camp & RV finds campgrounds, RV Stores (Cabellas, Camping World, Flying J, etc) and also does rest areas, picnic areas, parking areas, etc. That app costs $9.99 and includes the Wal-Mart finder as well.
