Some type of vent?

[CraigCam]

OK, I assume this is some type of vent? Is it electric and should I keep it? I can't find a replaciement for inside vent and cover?

The oval window looks like panoramic if I guess properly... not original.

The inside vent cover.. is that over the questionable window?

The cover on the roof looks like a repurposed AC shroud.

My front vent is a light/fan combo. It has a metal housing on the roof. Yours looks like a similar set up. It looks like someone made an extension on the roof and added an AC shroud for a cover.... Just a guess.

The photos are 90 degrees off. I'm pretty sure the vent isn't OEM, and if you can remove it without leaving a huge hole to fill, it wouldn't be the worst thing you've ever done for your trailer. I've seen those on Airstreams before, though not many. The ones I've seen have had a 120v fan in them.
