I like old RV's. But I don't think I could trust one on a road trip.
And, I get that someone doesn't post engine pics; not everyone is a gear head. But why wouldn't you post interior pics, especially of a RV? Inside is trashed? Well, say so and save yourself some grief when a zillion people want to see the inside. That said, I'd have to strip and re-do almost any stinky, old RV interior. Who knows "where it been"?
