Just to add our two cents. We have been doing this for more than 25 years, and full timing for over 17. At first we followed the toilet paper wars, which one broke down better etc. Then later we used and still use regular TP, we are constantly on the move except for 4 months in Florida for the winter so the tanks get sloshed a lot. Your house your rules is your business, but in this house there is no way the TP isn't going in the toilet! We also add Happy Camper to the black tank. We dump about once a week, we leave the gray open until a day before dumping, then close the gray valve, my wife does a couple loads of wash, a few showers etc and the gray tank is full. Then using our Sani-Con we dump the black then leaving the black valve open, open the gray to allow gray into the black tank, about 25%, then close the gray, and dump the black again, we do that until 25% is left in the gray tank and then close the black, and open the gray and pump the rest of the gray through the hose. Every month we use the black tank washer several fills, no problems so far, no plugs, no masses of TP, we have a clear section at the Sani-Con so we can see, no smells, works good. JMO
