Thank you to everyone who responded. Ingrid at StoneVos was really responsive. We just received swatches for all of the awning/topper fabrics they offer, including their exclusive vinyl product. These samples confirm our initial decision to go with an acrylic fabric. Their top of the line CoachGuard acrylic fabric is elegant and attractive, very well made and looks very similar to our original toppers and awnings. It also carries a 10 year warranty on the fabric, thread and workmanship. We are double checking width measurements today and will place our order. About two weeks from now, we hope to be doing our DIY installation of the new toppers. Our awnings are still good, but when the time comes we will replace them with CoachGuard as well.
