Problem is stacked dryer vent lines up almost with that window ledge. If I ran it straight out, it would hit that section of roof overhang. And then there's the matter of no access behind washer and dryer installed. I was going to install a Dryer Wall Jack in those boards to right of X in first photo, but it would sit below eave there, and dryer exhaust might be drawn into soffit vent. There just isn't any easy solution with an old house (1963 split-level) like this one.
