So it looks like the total length can be anywhere from one foot to more than two and half feet longer than the specs. I guess 44' it will be to be safe.
Looking to do a
raised center aisle building similar to link except with regular insulated garage type doors, 14' high in the center and probably 8' high on each side. I am on an acre but not enough room to do a pull thru, so back in it will be.
