Banana wraps are on the 4 corners of the trailer.
What your photo shows is the "under belly wrap"
That hole could be for the drain hose from the Air conditioner.
If your Airstream has an AC, it must have a drain hole as per the original design.
See if you can find an AC drain hose near one of the road side wheels.
