Absolutely there is.
I've since spent a lot of time and a bit extra money fully waterproofing it and it has held up well since then (I haven't used it much though especially since we bought the camper trailer) but it would have been handy to know before the Simpson!
That was an exceptional amount of wind and rain in Orroroo that night though which if we were closer to home I would be likely to pack up and go home if I saw that storm coming.
The next day though the sun was out and a nice dry breeze. Our tents dried in about 5 minutes!
