Toilet & Floor replacement Project, 92 Limited 34

[frankfarmer]

Relatively new owner, Just discovered rotten floor under toilet, 1.5 by 3 foot section has to come out!

New Sealand toilet, plywood, drills, small saws, tanks cleaned, entire area opened up & dried out. Rotten area under rear of older toilet extends under rear bulkhead into stern berth area, that area of floor/carpet also removed & opened up to be cut out.

Any advise, directions greatly appreciated.

Owned & lived on mega sailboats, repaired anything & everything on a boat/sailboat. Airstream is all new to me. No idea of the frame underneath, steel, distances apart, etc....

Thanks for any time/help.
