I have a 2017 199FKS with a 17 gallon black water holding tank.  It does not take much usage for the tank to fill rapidly.

Does anyone know if it is possible to get and install a larger black water holding tank?

If you look back a few years in the forum posts, you will see that there was an issue with some of the sink/shower drains feeding into the black tank instead of the gray water tank on the earlier 199s. As I don't have a 199, I never researched the details, but I believe Riverside corrected it later year models.
