Most sliding patios doors are really easy to remove both doors from the frame. Generally the sliding one lifts and then pops out, and there are two screws (one top, one bottom) holding the other into place, remove them, slide it over a little and it lifts up and out. Be careful, they are glass, and while generally tempered, they still break. Worse each panel is heavy.
Anderson sends their patio doors in parts and you put it togather, everyone else send the whole thing (which is heavy) as one unit, but often you can still remove those doors.
If I were helping you unload that machine I wouldn't let you stop me from removing the panels. I've also installed several patio doors (I worked as a carpender for a few months), so I have an idea how to do it. The only thing that should slow you down is the weather, it will get cold in the house while you do this.
