H3 and Privacy Glass

It seems as if some of the pictures I see of H3's have very dark windows (black looking) whereas others are not so opaque and you can see the interior shades. I cannot tell if this difference an artifact of the photograph or not. The Prevost Site has info on privacy glass, but I can't tell if that is standard or an option.

Is "privacy glass" standard on the H3 or is it an option?

I think all of the side glass on the coaches is tinted. I don't ever recall seeing one without it.

That does not mean you cannot see in from the outside under certain conditions, such as when looking straight through a coach from side to side as long as the blinds are raised.

At night people on the outside can see in if the lights are on or the TV is playing.
