Are Chris and Brittany from 1000lb sisters fundies?

This gonna be for people who watch the show so if you don't you might be lost haha.

For anyone who watches the show, Brittany (Chris's wife) has had a lot more air time this season. She wears a lot of religious shirts, only wears skirts and I noticed in the newest episode Brittany and Chris had to walk away when a haunted painting was brought up. Brittany was also not happy about dick jokes being made at dinner.

I know not everyone religious is Fundie, but the skirts only thing is what really stuck out to me. Has this ever been addressed before on the show? I don't recall them talking about their religion before really.
