Ask the manufacturer what height door they can put into the position you desire. If it's less than your desired height, then add the appropriate sidewall to get it there. Most highway bridges used to be set for a minimum of 13'-6" clearance. I wouldn't set the door opening higher than that.
Do you mean any lower than 13'6"?
X2. That's what I was thinking. I think Doug made a mistake.
perhaps he meant that anything over 13-6 was a waste? assuming that is still standard highway bridge minimum clearance height. i.e. no reason to put in a 20 ft high door.
