There was not one at the Rally.
We happened to see one, with that window in the bedroom. It was a SOB at the dealer that provides the rally attendees dinner.
At one of the seminars, it was pointed out that that will be a buggar with bugs upon arrival at camp. As you know, many campgrounds get rather snarky about washing down the rigs. Maybe just a squeegee and a little bit of water in a bucket?? Or some of the neato cleaning products available. But, really, who wants to look out this monster window through all those bugs. I thought it was a good point.
