I am putting the plans together for a garage and I feel I am making this more complicated then it is. I am stuck on the header size for the 16' door. My plan was to just use 2 2X12's with 3 jack studs and call it square. The door will be on the gable end. I just read that gable end trusses dont have much support unless you order the engineered type, would this be my best option to order the special truss or should I beef up the header. We do have snow load her in Mn but I'm hoping the snow slides off the steel roof.
