Confusingly, the final width is somehow exactly 3” less than my CAD model and drawings. I must have miscalculated or mis-measured something without realizing it, but luckily I did so consistently (whew), and 19’ 9” wide will be just fine. Being over would have been a fairly major disaster since I ordered a bunch of lumber in 20’ lengths — dodged a bullet there.
