Help re: plumbing/water tank/sink on 2006 T@b 320s

Hi everyone.  We just purchased a 2006 T@b 320s.  The pamphlet does not give any information on the sink, fresh water tank, or grey water tank.  I know there's potentially a lot of variability even among 320s models, but I'm hoping someone who knows what they're talking about re:  older models can help me with the following questions: 

• From what I can tell by crawling around underneath, this camper does not seem to have a city fresh water hookup.  Can anyone confirm this?  
• The water tank appears to go in with the spout on the top; the tank doesn't seem to fit any other way.   Is this correct?
• Do I need to loosen the air valve on the water tank for the pump to pull water from the tank?  Or do I need to keep it tight so that it creates suction?
• How big is the grey water tank?
• I see a standard garden-hose-size hookup under the camper, which seems to be for grey water draining.  Is this correct?  

Thanks in advance for any information you can provide.

Best,

Matt

• May not have city water hook up.  Would be on driver side near front.
• Water tank - Spout on top, air cap loose.  Gasket between dip tube and pump line - tighten snug.

• No grey tank.  Most times, we use a bucket under the drain fitting.  There are small portable tanks available.  Should be a cap for fitting during travel.

Thanks, rfuss928.  Is the "dip tube" a tube that goes from the water to the spout?  Sort of like a straw?  If so, my tank doesn't seem to have one.  That's the thing that's been confusing to me about this setup.

Yes, a long straw that goes to the bottom with a top hat like flange at the top.  Keeps it from falling into the tank and mates with the pump line.  Gasket for between flanges is seen in top of cap.

Thanks so much. I was able to assemble something functionally similar out of materials at my local hardware store
