While you’re waiting for people to respond with direct experience, there are some reviews online (if I recall, 5 stars from 5 reviews on Trustpilot- not where I’d think to look but Google went there). And check UKCS reviews too.
We had one when they first came out and unfortunately it was taken back. Zips were very cheap and leaked like a sieve. The dealer didn’t argue when we took it back either, so I assume we weren’t the first! They may have improved as this was a few years ago.
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
