Great mystery. This is in a 2007 Kountry Star 3910. There is a cut out out of the wood panel below the cupboard where the washer/dryer is. In the bedroom, to the left of the wardrobe. It's a metal grill with very small openings. I can't find a way to open it, or see what's behind it. Really puzzled as to what it does, why it's there, what's behind it, and how do I get to it? Thank you!
