what is this vent for?

Still trying to get the layout of my '58 Overlander. This might help. There is a hole in the floor about 4 inches across near the front door and below, in the belly skin, there is this vent: Can anyone tell me what went above this hole/vent? Thanks

Maybe it was lol. I don't have one. There is an oblong vent in the roof above it. Why is the vent so big but have only one hole? I'm afraid vents have been added through the years. I'm having a heck of a time figuring out where the oven and fridge went. If the fridge did go here, there is a copper propane line coming up about 3 feet to the right of this. I assume this is for the stove. Did Airstreams come with the stove and fridge on the same side? I've never seen one.

Your model is older than I'm familiar with, and I'm sure someone that knows it will come along, but I'm willing to bet that it was where the refer was.

They require a floor vent and a roof vent. LP gas is heavier than air (floor vent) and heat needs to leave (roof).

Good luck with it!

That makes sense, thank you!

Check this site if you've not done so before. There's a pic in trailer 7076 that has a vent that looks a lot like the roof vent your showing.

I'll bet it was for the furnace, the floor vent gave the furnace fresh air to burn which vented the fumes out of the roof. Those old furnaces were convection with no fan.

I have a 57 Overlander and it has a similar hole/vent below the furnace Im guessing it was for combustion air.

furnace air supply

I believe it is for the furnace...inlet air supply. If so, look at the ceiling above and see if there is an exhaust vent hole....probable covered over.
