I'm confused about how you worded your response. You're saying I'm right and it's too narrow to have 3 2x4's? 1.5+1.5+1.5=4.5" plus one layer of 3/8" drywall on each side is 5.25" Also, I do not see a jamb in that pic and am assuming it's like my current apartment and it's just an outside corner on the wall (just drywall wrapped with a corner bead and the window is recessed).
