Hello, AsFire. From looking at the plans, here's what I got:
Bow area: Cargo or motor car storage, 1st and 2nd class baggage, Specie Room, Parcel Room, mail room, and cargo space under the No. 1 Hatch (I think)
Midship Area: Boilers, steam pipes, the coal bunkers, etc.
Stern Area: A ton of things. There is a thawing room, east bound beef, west bound beef (No clue what those 2 are), there is refrigerated space for cargo or provisions, a refrigerated cargo space area, dried fruit, wine and spirits, groceries, champagne, mineral waters, tobacco and cigars, and cargo space under the No. 6 Hatch (I think)
