I've actually never seen one that slides. If there is one thing I don't like about this floor plan it's the lack of a window due to the wardrobe slide. Everything else I love. I've got AC up front in mine but, if I didn't, I'd put a power fan there. I'm assuming you're looking for more ventilation. The power fan would be an easier / cheaper way to go if that's the case.
