I agree with RCW and the same applies to those nights we stay at Flying J, rest areas, or Indian casinos. When we are "traveling", not camping, we want easy-on, easy-off access, a secure, lighted parking lot, and maybe a few groceries or a quick/fast food meal. And Walmarts often meet those requirements. We have ear plugs and blackout shades to take care of the road noise and nighttime lights.
Before we bought our first RV, we avoided Walmart like the plague, but now, with an RV, Walmart is our friend. It is our preferred stop to buy/replace a leaking potable water hose, a broken sewer line connector, a 30A power cable extension, toilet chemicals, RV toilet paper, DEF, a telescoping RV wash brush, flashlight batteries, and even new rear truck tires (in Whitehorse, Yukon). So, we certainly leave plenty of our RV travel $$$ at Walmart!
