Anyone using a cassette toilet in their B?

I prefer the idea of a Porta-Potti and finally got to try one because the PW Traverse came equipped with the little ones. Having dealt with black tanks on three previous RV, the PP was easier. Still don't like dumping but it is less of an issue. My dream RV would have onboard water, primarily for a shower, not kitchen or toilet use. In my Traverse, I can't remember when I used the onboard 12 g water tank. I carry a 4 gallon Reliance blue cube in the sink and set it on the counter to use for teeth brushing, handwashing, etc. I don't wash dishes (use paper and plastic cups and utensils). My trips are rarely longer than 3-4 nights. Simple and easy is what I want. The Porta-Potti is there for emergencies but I think I've used it less than a half dozen times in the almost 11 years I've owned the rig. It's a shower I miss.
