My 1977 31' center bath only has the two you mentioned (unless there is one 
that has been hiding :-)

The unit wont have a bypass valve, unless one was added later on.

I added one to my trailer. Installing it involves removing the toilet and 
the plastic cover over the water heater. I used a "standard" bypass kit 
that's sold in RV supply stores, but I modified the installation. To 
facilitate access to the bypass valve, instead of installing it directly on 
to the hot water tank, I did a bit of custom plumbing and installed it 
in-line to the input & output lines, to the left of the hot water tank 
(underneath the sink). Now all I have to do to access it is remove the 
access panel below the sink.

Yes it does. I have photos of my Fantastic-vent installation online at:
