I doubt it is "one way glass" but will be dark tinted like many units on the road. With the dark tint you can't see in during the day but at night, with the interior lights on and windows open you are in a "fish bowl" as we say. I do believe the big front windows have a privacy screen if I recall from the ones we have looked at.
Here is a link to a walk through of the unit. Note at about the 7 minute mark they talk about the front window and the privacy screen.
