I just got the new cabellas catalog.  In it are several marine poly tanks.
A couple are under 8 inches in height.  I am currently doing some measuring
and stuff to possibly put in one of those under the sliding door side.  I am
considering fill from the rear with a syncho filler leading to the tank.
However funding will deter any actual purchases at this time.  Strictly and
achademic design phase to check probablility at this time.  I have also
considered putting in a flap just inside the sliding door floor with seals.

This is actually the most practical method but not a preferred one.
