Incidentally, I wanted to make a recommendation for the 'high lift' garage door design I choose here to anyone considering building a garage or replacing their door. With my ridge pole design, I have ~11ft of clearance at the outer edges of the door (15' in the middle), so I went with a door design that rolls up 3 ft before making the turn and rolling back horizontally. This means I have over 10' of clearance between the floor and the tracks, and the door when it is open. The opener is 'jack shaft' variety that sits on the wall next to the door, rather than overhead as well. You can barely see it at the top left in the photo above (small black box, above the white light fixture).
This design costs a bit more (about $75 more for the track, and $200 more for the motor) than a standard garage door would, but it is absolutely worth it in my opinion if you have the ceiling height to work with.
