We had a factory installed Sani-con in our last coach and while it was convenient to use and stored in much less space, I found that it required periodical maintenance to keep it running efficiently. At least once a year it had to be removed, disassembled and cleaned out. Hair would wrap around the blade shaft and on two occasions I had to replace the plastic (?) impeller. Dumping time required five to ten minutes to empty and clean both tanks...kinda a downer when it was raining.
However, on the plus side it provided the capability to use the gray water to flush out the black tank...really handy! Using it at home allowed me to pump the tanks to our sewer clean out opening about 75 feet away. While on the road, it was simple to use, just pull it out and stick it in the sewer opening.
Our new coach came with the standard stinky slinky and while it does take up more space, it requires much less (if no) maintenance and will empty both tanks in a couple of minutes.
I removed the Sani-con from our old coach when we traded in so that I could use it at home, and thought seriously about using both in the new coach. Eventually, I decided that we really didn't need it, and I leave it at home.
Hope this helps
