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.

Most RVs have AC, ovens, TVs, and other luxuries.
To much of the world, living in an RV is living well.
