Black Water Tank Missing Capacity
We just bought a used 2015 Cruiser RV Fun Finder F233RBS. It is a 24 foot travel trailer and we love it. We have been RVing for awhile so I'm knowledgeable about tank maintenance on these types of RVs...

Easiest way to make sure is to crawl under the trailer and look at what is marked on the side of the tank. Then you know for sure. I would guess that there is a "downpipe" where the toilet is mounted to the tank that extends a few inches into the tank. When water reaches the bottom of the pipe, you end up with an 8 gallon trapped air bubble.
