Wal Mart = convenience.......when we travel we stay at campgrounds 99% of the time. BUT, when I want to get some miles under my belt, I may drive till 10p.m. and simply want to pull off and rest. If I don't need supplies a flying J or a rest area are fine. If semi trucks park there so will I. When I do pull in to a walmart or a rest area or a flying J I come in late and am on the road at the break of daylight around 5:00 a.m.
I guess I just don't see what all the discussion is about.....The beauty of having a motorhome is the ability to STOP WHEREVER YOU WANT. If you don't want to don't do it. END OF STORY!
