For us, the biggest attraction to driving cross country in the RV and staying in campgrounds is the people you meet. The managers of motels tend to get upset if you start a campfire in the lobby just so you can meet your neighbors. Another advantage is the campground. Usually secluded and somewhat natural. Yes there are exceptions, but most motels we've stayed at are on frontage roads facing fast food joints, auto parts stores, shopping malls, gas stations, etc..
Well said, Chris. This is what tips the scales.
