I have had RV's for over 30yrs and I have never bought RV toilet paper, never needed too, the trick is to use lots of water when you flush, if there is anything solid in the bowl make sure you fill the bowl then flush, I have never had anything plugged up, I also use odorless chemicals, supposed to use one scoop, I use 2, and I always use a cap of calgon water softner to coat the walls in the tank, so I always get a good flush, I have a back flush I use to make sure thae tank stays nice and clean....works for me
