2017 AI GT EXT black tank access?

[rajsingh]

The grey and fresh tanks are under the chassis and easily accessible from below. The black tank seems to be onboard looking at then drainage plumbing on the bottom. Does anyone know how to access the back tank? I am trying to replace the tank sensors.

On my 2018 GT, the sensors are on the front end of the tank, accessible by removing the grille below the refrigerator. The tank, itself, is trapped in place by the bathroom shell.
