Do you use your bathroom? If not, what do you use it for?

RV is designated as 'self contained'

That means you can sleep in it, cook in it, wash dishes in it, entertain in it, poop in it, pee in it, shower in it without having to interface with any other facilities.

Yep,........we do ALL of the above.
I even sometimes pee in the shower.
Such is life.
