We stepped down from a hybrid travel trailer, which had a full bathroom. The convenience of having a toilet for middle-of-the-night calls of nature was something we weren't giving up.
I didn't care much at all for the cassette potty that came with the camper. We had good experience with a Thetford cassette potty with one of our old popups, so I bought one at Cabela's. I picked up the tallest one they had that would still slide under the rear bed, so it could be stowed easily in the daytime. During the day we use the campground's facilities.
We have a camper-potty motto in our family that we stick to. "Everybody sits, and nobody $h*%$."
