Sunshade/Canopy

Hi

We're looking for a canopy/sunshade for our caravan.  The only ones I can find on line are the Fiamma/Caravan store ones or ones that look like a full awning without the fronts.

What I want is a piece of canvas (or whatever) that pulls through the awning channel and then has 2 or 3 poles at the front to hold it up with guy ropes off.  Nothing fancy or complicated, for those short weekends when you just want to keep outside the door dry or a bit of shade.

I saw one at Blackmoor at the weekend but the caravan had gone the next day before I'd had chance to ask where they'd got it from.

Any ideas?
