Bath and A Half??

I have a bath and a half. They just put a 2nd black tank in under the 2nd toilet which also collects that sinks drainage. I have 2 blacks and 2 grays. The 1st black and 2 grays go out one connection and the 2nd black goes out a 2nd connection near the rear door. It's pretty neat when all the grandbabies and kids need to use the restroom they can get to it without running through the trailer. Both blacks have flush connections.

We like having the 2nd toilet.
