Thank you @jkjenn!

These are great photos.  I'd like to know more about what are the important focus points of each.  Do the blue and red pipes have significance?  Blue = fresh water? Red = hot water? Is Photo 1 the water pump?  I see what I think is the Alde safety/drain valve in the center of photo 5, right?
We have a 2021 320S and are still learning, so any help is appreciated.

Blue pipes carry cold water, red pipes carry hot water.  Photo 1 is the water pump with the filter housing on the intake side of the pump (just left of the pump).  Correct -  photo 5 yellow flapper is the Alde Safety/Relief drain valve.

Photo photo no 5 shows the yellow Alde pressure relief valve (yellow flip up handle in center of photo, blue tube going in, white tube on other side.  Flip the up to drain off the Alde water tank, with hot water valves open to let air into the tank.

Did nucamp relocate the water pump from behind the toilet, or is this an auxiliary pump of sorts?

The water pump on both the S and CS are under the bench as of 2021.  The glycol expansion tank is behind the panel under the wetbath built-in sink.

The location makes a lot of sense on the 2021 models. It is close to the Nautilis and makes filling the freshwater tank via a siphon method with the pump very easy.

@Sharon_is_Sam 's comment made me think, why is the glycol expansion tank so far from the Alde unit on 2021? Is it easier to fill in the new spot. Wasn't earlier models right above the bench?

The pre 2021 model glycol tanks on the S were in the rear driver side corner and required a screw driver to remove a wood panel to access the tank.  The CS model tanks were always behind the hatch above the toilet and easier to access and fill.  I think the relocation is good for monitoring and filling.  The new 2021 sink now occupies the wall where the hatch was previously located.
