I noticed two holes in that location in mine, but with metal plugs - and I've seen no other signs of the hot-water heating unit (Officers, For The Comfort Of) that was supposed to be in that location in the rear cab. I'm guessing that the heater was never installed at the factory.

I have some other holes in the cab floor here and there, roughly cut, about 1" diameter, but I'm not sure what the purpose is.

Those holes in the corner behind the driver are for the vents of the transmissions,fuel tanks and axel housings all come up in the corner and vent up to the roof..
The dog house horse shoe is for the breather hose for the carb...
According to the Ford wadeproof manual..
