Having been an avid camper for 50 or so years, and watching the changes that have taken place over the years I would be really surprised to see much of the population RV'ing 25 years or so from today. Boondockings days are numbered in the west, which will impact many. Environmentalist pressure, along with taxes based on miles driven as well as weight of vehicle, time of day driven etc will also have a very significant impact. I would expect the US to thus become much more like the more densely populated countries in Europe where few members of the population camp in any way shape or form.
