Don't feel blond, here's the story of gray. When I purchased my first camper (24' HiLo, donated to a church and then resold to me) it came with no history, maintenance, records, docs, anything. And I had no knowledge of campers.
The shades were closed (in the full privacy position) and I didn't know they did what they do. Several months after cursing the darkness I nearly cut them out. Many more months later I accidentally discovered they raised to the mid position. Of course then I was quite happy I hadn't removed them. BUT, many/many months later I discovered a third position ... completely open.
My bride was just as surprised by all this - as I was.
