Looking to find the title of this book

Hey, I read this book a couple years ago and I want to reread it. But I don't know the author or title and I can't find it online. What I remember is it's about a black guy who calls himself preacher and his and his community are Christians. They live in a caravan I believe. He has multiple girls, they also smoke weed. They're trying to get the church to be successful again and I remember at the end he's even on TV and all that. There's more to the book but that's all I can remember. Every hint is a help thank you 💕😅
