The article comes from the same reason I'm running the A Buck A Plate blog http://abuckaplate.blogspot.com - doing it because so many think living well for cheap can't be done.
Why do people here have such a fascination with toilets?
The way a regular toilet works: Water automatically enters the bowl. You do your thing. You press a lever.
The way an RV toilet works: Water enters the bowl when you press a pedal. You do your thing. You press another pedal. That's my toilet anyway. From the perspective of one's posterior it's pretty much the same thing and you can do all this while sitting on the throne.
Some RVs have flush toilets or even vacuum toilets.
Most RVs have toilets. And beds. And stoves. And refrigerators. And heaters. And other major amenities. Heck, the toilets even use _drinking_water_ to flush - such wasteful luxury. Never mind the ability to just pick up and go anywhere anytime.
Most RVs have AC, ovens, TVs, and other luxuries.
To much of the world, living in an RV is living well.
