Works Pretty Well in the Ford Transit Too
I purposively bought the this curtain after comparing dimensions between the Sprinter and the Transit. It's slightly long but the width is almost perfect. I don't have rear AC so I needed a way to keep the cab cooler. I tested it yesterday in 107% weather. Much better than trying to keep the entire van cool.
I have the recommended shelf with curtain rod. My only complaint is the curtain rod is directly over the seatbacks. The curtain cannot hang straight down as a result. I might consider putting in another curtain rod further back.
