Kelly, I'm not sure if you have seen this thread:

"John, Toilet, Head, Potty, & Crapper Talk"
There is a good discussion of RV toilets there. The thread title is not the best to find, it may escape the search feature.

Hi Steve! Yuop found it ....read it, a couple of times in fact! Riveting stuff! : )
