I think the problem is that the average age of most viewers is probably 10 to 16. They don't want to see snowy mountains day in, day out. The older three girls (who the majority of the Ifam are interested in) wear the same clothes day in day out, there's no shopping hauls, no teenage chat etc. The Ifam hero worship the older three, they want to see shopping hauls, make up tutorials, dancing to Taylor Swift, boy chats, going on sunny Holidays with beaches, theme parks and so on. A lot of the Ifam will wish they had that lifestyle. They don't want to see van life, they find it boring.
Chris is the reason the channel is failing.. He's obsessed with van life and cold, snowy countries. It doesn't matter to him that the Ifam don't enjoy watching that type of content, it doesn't matter that the older three kids don't enjoy long trips in freezing conditions and that it's dangerous for the younger three, all that matters us that it's what HE wants. The kids would be much happier on an all inclusive package holiday, lazing in the sun and playing in the pool and that's what the Ifam want to watch. It's hardly rocket science for a very lot big genius like Chris.
