Richard Klein, a mechanical and aerospace engineer with more than 30 years of experience in vehicle dynamics, was among those addressing 82 representatives of 38 RV manufacturers and suppliers on the stability of trailer design during a March 5 seminar hosted by the Recreation Vehicle Industry Association (RVIA) at the RV/MH Hall of Fame in Elkhart, Ind. Klein reviewed decades-old, safety-related engineering data, according to Bruce Hopkins, RVIA vice president of standards and education. “It appears from listening to Dick Klein that there was engineering information out there for 30 years that is valid today that only a few people knew about,” said David Mihalick, Thor Industries Inc. corporate standards compliance manager. “The seminar got us back to hard engineering data.” In addition to Klein, seminar speakers included consultant Harley Holt, president of Harley Holt and Associates Inc., and David Kinder, a partner with the Texas-based Cox Smith, a law firm that has represented RV manufacturers in cases involving claims related to travel trailer stability and rollovers. “The seminar provided a number of recommendations for the manufacturers to look at,” Hopkins said. The event was sponsored by AL-KO Kober, Corp., Dexter Axle Co. and Norco Industries.
