I was blessed today to get a used but in great shape, dark tint Madstad,for free. I think it's a 13" (measures 12" overall). The local dealer bought a used 06' RG with the MS. I had a 14" windvest. They didn't like the look of the MS, but didn't want the WV. I had a used, once out the box 15" hd windsplitter that was given to me. They wanted that and jumped at the swap offer. I need to lift it an inch or so, but even at it's lowest setting it works well on the RGU with stock sofa.
