When my wife needs the restroom right now, I unlock the door to the trailer and the crisis is averted. That was the motivation for buying our RV after my wife had a stroke at 42. the RV gave her the confidence to travel again because she knew that if she needed the bathroom, it was right in the back. Funny thing, the 8 years that we had that RV, neither of us ever used the bathroom in it. It was a Toyota RV with a tiny bathroom. We bought a TT with a dry bath so that we could travel with more convenience and now the bathroom does get used.
