What appliances align with the openings in the skin ?

[Aktundra]

I am finishing up running the wiring, and will be getting appliances once I get the internal skins back on.

Based on my research this 1963 Bambi originally spent most of its life in Florida, and by the time I got it, it had no furnace and this circular patch between the water heater opening and the door.

Is the circular patch where the furnace vented ? Can anybody give me some info, on what model/brand furnace & water heater that can keep me from punching another hole in the skin ?

The round circle is the trailer heater and the modified drop down the water heater. You can scan the pictures on my website (www.bambiairstream.com) of my reno and see pictures of both.

Do you know if there Is a current model that will use the same furnace opening ?
