When we got our first TT, I did not want anyone using the toilet. Worked ok for a couple trips, as we were accustom to using campground facilities and we always reserved spots close to the restrooms with our pop-up. Then we took my mother with us on one trip to show off the camper. Well ... we told her "no potty!" She did anyway! So I learned how to dump on that trip and been doing it ever since. Wife now says, we've got the thing to use, NO MORE PUBLIC BATHROOMS OR SHOWERS EVER AGAIN! So I now make 'dumping' part of the camping experience! (I have to admit ... she's right!)
