If you would like a cassette style awning I would suggest you look at the Aussie Traveller Coolibah Awning. They are a little heavier than the European style types. They are wonderful in windy conditions. I sit under mine and watch all those with roll-out awnings roll them in and out as the wind conditions change.

I started using them as I will not attach a roll out awning to the top of a pop-top van. In the early days, I had observed how those distorted the pop-tops on vans. I was using the old sheet with annex poles until I discovered the Coolibah Today I would consider putting a Coolibah on any van. They handle stiff breezes better than roll out types with the anti-flap bars in place.

In the link I showed above, there is a demonstration of how to erect them. It is shown on a camper trailer but the same erection applies on caravans apart from the way the correction of the camper trailer lid is involved. There is a little more time taken to erect them than erecting a roll out awning and tying them down. but less than if you are putting on the anti-flap bars.
