Elddis Avante 362 porch awning advice, please

 Hello there, we are in need of some advice. We just bought our first caravan, an Elddis Avante 362 Club and are now looking for a porch awning to fit this van, to be used in spring/autumn weather mainly. The smallest ones I can find (like Dorema Alpha) will come to just on the sidewindow. We would like one that does not obstruct the view, are there any Avante 362 owners that have a suggestion? Also, does a rear padded pole scratch the window? Thanks very much for any advice. (Sorry Rowena, I first posted this on the wrong section of this wonderful site!)
