+1, Bill. Double ++1.
Eighteen years of pooping and flushing in the Electramagic with never a smell or "tank cleaning" issue. I don't even understand why you would try to "clean the tank" in an Electramagic. Sometimes as many as 4 adults and 5 children share the pooper, but usually not at the same time
We DID have a flushing issue (stuff wouldn't go down), but that was immediately remedied by removing the skirt.
The "bottom line" (sorry!) is this: if I had to go to a campground toilet, or carry a cassette full of the family business to a campground toilet, I'd get a different RV.
