If RVing is no longer a more affordable option than traveling by car, the entire industry will suffer. The ability to save money by boondocking on the way to our destination (which is most likely a campground or RV resort) benifits the entire RV industry - from manufacturer, to dealer, and campground owner. The money saved will likely be spent at our destination (we may even stay a few extra days).
We spend a lot of money to buy, register, insure, and maintain a self-contained RV that gives us the option to boondock. Now we find out it's illegal almost everywhere? We may as well sell it, travel by car, stay at motels and eat in restaurants. They could use our business too.
These four, unique, web sites are one way to fight back. Each is well worth the annual low-cost membership:
