Gemini 2018

[Cbedd]

We bought a 2018 gemini class b there is a Winegard thing on the inside ceiling and some kind of thing on the roof. Dealer never told us what it is and can’t find anything in my paper work. Help please.

I believe it's an "Amplified Local HD and Digital Broadcast TV antenna
for VHF & UHF digital and HD TV channels". You have to switch between cable and "air". And then do a scan.
If you go to https://www.thormotorcoach.com/owner-resource/ and use your VIN from your chassis, you can see manuals for all the equipment on your rig.
