[VAC] Re: Floor repair/replace question

Cruiser -
I think the floor registers may be original equipment - Airstream ducted
heated air under the floor to keep the pipes/holding tank(s) from freezing
in colder climes...

To patch those openings, i'd be inclined to glue-and-screw some 1x2 strips,
or a solid piece of 1/2" OSB across the opening from the underside of the
floor, and glue-and-screw the patches into them from above.
