March 2016 - This American RVer show focuses on slide-out toppers and awnings. Chris Throgmartin from Stone Vos talks to Jim about replacing slide toppers. He tells us what you need to know about making an intelligent decision on the material to use and the thread that should be used by a topper manufacturer such as himself. This is a really informative show for anyone who has an RV with slide toppers or awnings.
