They are cheap for a reason they are Chinese and the quality shows.
We had a full awning, Savanna I think was the name we used it once it was awful, The Zips were cheap and nasty I took it back to the dealer he kindly took it back and I brought a Bradcot a lot more money but you only get what you pay for.
Just my humble opinion.
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.
