Concerns about the TM bathroom and toilet.

We just bought a new 2720SL TM. We are waiting for it and hope to get it soon. I am excited and anxious both about owning a TM. It has been years since we have camped, and that was tent camping. One of the reasons I quit camping was that I didn't like tent camping anymore, or using the public restrooms. I've read many postings that were very helpful, but also read some negative postings about the toilet on the TM. Realizing that the bathroom walls on the trailer didn't go all the way up, and then reading about the toilet problems, I became horrified. Even to the point of not being able to sleep. All the more when thinking about our grown family, or guests going with us at times. I have issues with non private bathrooms, and close quarters with a possibly smelly bathroom.. Does anyone have encouragement to offer? Thanks!
