Also, forgot to mention to get the superstructure up, the door set so that it opens and closes properly, and THEN seal whatever the attachment is between the canvas and the door frame. On my Palomino, it was velcro, and on the Jayco, a small "friction" slide-in strip (the salesman said it was magnetic, but the frame is aluminum - I guess he failed sixth-grade science...).
If the attachment seal is secured before the door functions properly, then the velcro (or whatever) will hold the frame at the wrong position, and cause rubbing, jamming, or gaps.
