well, tp provide the side shade panel, I've got some outdoor lightweight fabric to which I'm going to attach a bright panel depicting beach huts and peeps frolicking in the sand. this will be moveable, depending on where the sun is. Wishful thinking at the moment with the cold we've had, but I'm sur the sun is out there somewhere.
Hob, I found an equivalent of the strip you posted over here so that will take care of the caravan side of things.
