Manufactured homes
5% of homes are mobile or manufactured homes, whose windows usually sit in thin walls with little depth inside the opening. An outside mount on a frame is the reliable choice there, fixed into the framing around the window rather than the thin wall panel.
Rounded drywall corners
62% of homes here were built from 1980 on, and many houses of that era have rounded ("bullnose") drywall corners around the windows instead of square returns. A shutter can't sit flat against a curve: choose an outside mount with a frame that clears the corner, or an inside mount if the flat part of the opening is deep enough for your louvers.

Cold winters
With 105 freezing nights a year, warm room air meets cold glass for months. Shutters closed tight overnight hold that air against the window, so condensation can collect on the sill: tilt the louvers open in the morning, and wipe the sill on windows that often run wet.
Humid summers
Hot days and 45.8 inches of precipitation make for heavy summer air. Wood swells when it's humid, so give kitchens, bathrooms and laundry rooms some air: run the fan after a shower and tilt the louvers open so steam doesn't sit behind them.
