Location of Alde expansion tank on 2021 T@B 320 CS-S

Where is the Alde expansion tank on the 2021 T@B 320 CS-S located?  I want to check glycol levels but can't find it.

Thanks!

Thanks so much.  These links are very helpful.  The location of the Alde expansion tank is not obvious and is not described in the manual.

This helps me a great deal also. Just took delivery on a 2021 320 S and I am appalled that there is no complete and accurate plumbing diagram.  The Nucamp user manual is not current in any number of ways and is far from helpful.

There have been several plumbing diagrams posted here for the TaB.  Issue seems to be, nüCamp would make minor changes during a given build year, so a definitive diagram is not really possible for every model.  But they are generally all very similar, and easy to sort out.  That said, many parts of the plumbing is not easy to access, and the bits that need regular service are easy to get to and find, like the water pump and filter, but this location changes from model to model and year built.
