I have a 2013 Thor Daybreak 32HD, the shower door is hitting on the bottom outer edge, not the hinge side, it looks square except for the bottom. I don't see any way to adjust the door. I have replace the lower seal, and it is torn up again. You have to pull up on the door to open it. It is a glass door between 2 straight glass panels along the top of the tub. Any Ideas?
