Our front roller shade when fully down had a 3/4" gap on the left side, had been a pet peeve every since I got the coach, finally got around to fixing it. There are four pairs of mounting screws for the shade, I added a pair of 3/4 inch spacers and longer screws on the far left, the next pair got 1/2" spacers, next two pairs left alone. MUCH better now!!! Good thing I have long arms, I'm to heavy to get on the dash!
First photo is left side gap, picture is sideways. Second picture is right side which was down on the dash like it is supposed to be. Third picture is a nice and level shade!!!
