I am getting ready to frame up my garage. I live on a 3 acre parcel and unfortunately I am restricted to the height of the building. The best I can do is 10 foot walls. Just wondering what door height you might have for your big bolts that gives you clearance. I don't have a bed on mine yet, but I could make a removable headache rack on the back. I would think 8' would be my best with the header, top plate and trim. Is that good enough?
