I agree, a sanican system is just something else to go wrong. Its no different that anything else. As long as there are new people to a certain situation, there are going to be people that prey on their inexperience and fears. You have a 3 inch diameter hose, not too many humans have excriment that large. If you are in a CG, just use lots of water. If you boondock, use a good bacterial digester that breaks dowm solids quickly, which allows you to use less water. Personally, I use RV Digest-It, it breaks down orgamic solids quickly and eliminates odors. I use it at CGs as well as boondocking.
I don't use chemicals that can kill bacteria and don't flush my tanks for the same reason
