Sun canopy

spk

Can anyone reccomend a sun canopy for a caravan (only needs to be 3m long) that has an end (or a back whichever way you want to put it) and one that is stable in wind ?

We have a standard cheapo sun canopy but it is far from rigid and useless in wind, we usually put a tall windbreak around the back and the side to enclose it so was wondering if there is a suitable product that has a "back" to it.
