[a/s] The dreaded rear bath version in my 27 foot 1973 Overlander Airstream

["Vincent Comunale" <vcomunale@xxxxxxxxxxxxxxxx>]

I was unaware of the sagging problem I've heard about at the time I
purchased my Airstream this past September. There is no evidence of damage
that I can determine so I guess I've been lucky.
I cannot find the existence of a discharge valve for a gray water tank, just
for one for the black water tank which is located in the outside rear
compartment. Water discharged from my shower & sinks seem to flow directly
outside into the sewer system. Is it possible a gray water tank was never
installed?
