Installing front roller shade

Has anyone installed an MCD dual roller shade to replace their front curtains? Our 2015 Winnebago Vista has the curtain and also 2 small, virtually useless sun visors. A friend just bought their new Class A (different brand) with the roller shades and riding in it with the ability to lower the power sunshade was such an improvement over visors, I'm going to bite the bullet and add the dual rollers. My concern is the guides on the a-pillar trim. My Winnie just has a flat trim while 2017 Winnebago Vista LXs I've seen have a trim piece with a raised forward lip that acts to guide the single roller shade they come with between the trim and the windshield. Is there anyone reading this with a higher end (Adventurer) Winnebago, 2015 or later, with the dual shades? I believe they come with a trim with 2 slots to guide both the sun screen and privacy shade. If that is how the trim is made, could they call their dealer and get the part numbers for the 2-groove trim pieces (left and right)? I've spent time on the phone with Winnebago and it was finally decided without the VIN of an Adventurer, the parts guy could not find the part number of the trim so I could order it. I'm quite certain that starting in 2015, the trim pieces are interchangeable across the Winnebago Class A gas coach lines. Thanks in advance, Gary
