What is this?

Trying to figure out what this is behind one of the cubbie doors on the back passenger side. Its just a door with this little plastic jug behind it. Anyone know?

It's where the spare dilithium crystals are kept for the Triton V10 warp drive.

Looks like a hydraulic tank for the stabilizer jacks....and it looks empty....NOT GOOD! ...or could be for a hydraulic slide.....in any case should have fluid in it.
