Do you know what this is?

[rwbradley]

Does anyone have any idea what this could be? There are 2 of them in my trailer. Both are mounted on the roof near the tent ends of the trailer. The inside looks like a 1/4" headphone jack. The dealer I bought the trailer from does not normally sell that brand so they were not sure. They speculated that it was a DC power jack for plugging in a fan or light that hangs inside the tent ends.
Any thoughts or ideas?
Thanks

You should provide information about your camper...have you called the camper manufacturer or the nearest dealer for your brand?

I have been looking but I have not seen anything like that for sale anywhere. Is it a custom item? Any idea where one would find them?

That's it.
