Porch awnings

Hi again folks , we are looking for recommendations for a new porch awning for our new affinity 550 we are hoping to pick up in the next couple of weeks , on our last van a swift challenger we bought a  kampa air 260 but we sold it as we found when we were in a sloping pitch the air beams didn't seem to sit right ,ie slightly buckled , we also had a lightweight kampa 200 for winter use as it was easy to dry at home . We would ideally prefer a 330 but on the 550 it would cover about eight inches of both Windows and my fear is that it we would damage the Windows with the storm poles so may need to stick with a 260  , the long and short of it is we don't have any local dealers who stock awning so would like anyone's experience before parting with any monies to the tinterweb , full awning not an option Tia
