No more Walmarts since we obtained Sporty/SMB. When we slept/camped in our SUV. We stayed there a lot w/no problems (though) some Walmarts are as "sketch" as they come and we wouldn't stay. Most have signs IF you are not able to (ie part of a strip mall that will not allow bc other stores). We found that 5am brought out loud pickup trucks taking pictures/scoping the van out, but waking us up, booooo. We then started looking for Sams lots...MUCH BETTER!
As the years went by, we gave this up totally. Now IF we can't find a spot or are in between destinations, we look for Cabela's (we call MGR of store and have ALWAYS had a "ya sure"), Cracker Barrel (lots are usually very small and lot WILL BE FULL if you sleep past 8am lol) but GREAT takeout breakfast (lol)...Tourist(y) spots like Florida coast towns, we blend in like member "Two" spoke of and look for a Ford dealer's lot (well lit and can have lights on inside), a hotel lot or just off the street of sd hotel, which we have walked into in the AM (looking like a guest) to use bathroom. Lastly, SOME states have really nice Rest Areas that are well lit, somewhat busy, sometimes patrolled, off HWY a bit and with our white noise machine, a great spot to sleep...BR facilities and sometimes great vending (lol)...good luck!
