Holding Tank Installation Questions

I'm finally facing up to the inadequacies of my late-1980s holding tank installation; would appreciate advice out there from those who may have been brave enough to go down this road before.

My leading scenario is to put a tank with ~80 gallons capacity (48" long) under the port berth in the dining area, having someone manufacture a custom tank to fit the contours of the space. I would then create a large access port in the side of the locker, replacing the current fiberglass with marine teak.

Among my questions:

Is this the best location?
How have others arranged for access to the space (alternatively, I could cut into the horizontal surface beneath the bunk, but this appears to be potentially more of a structural issue)
Is it worth the added complexity and expense of a custom tank to accommodate the angles created by the hull shape, or should I just go with something that is rectangular?
I would appreciate any advice that may be out there....

sOn D.W> Crow we have an 80 gallon stainless steel holding tank that was pressure tested to 80 lbs. mounted under the port side settee seat, as you are considering. The tank was inserted from above with the horizontal surface of the seat being cut out for access. The vertical surface of the seat continues to provide longitudinal support. There doesn't seem to be any issues with the hull. Hope this is useful.
