ASV was formed in 2010 from the merger of four American Industrial Partners companies. Later in 2010, ASV acquired the Road Rescue company, a manufacturer of ambulances, from Spartan Motors. In 2013, two acquisitions were announced. SJC Industries was purchased in May 2013 from Thor Industries. It is a manufacturer of ambulances under the brand names McCoy and Miller and Marque. A week later, it was announced that ASV was purchasing the RV assets of Navistar International, which include Monaco, Holiday Rambler, R-Vision and the Beaver and Safari brands. In August 2013, ASV also announced the purchase of Thor Industries' bus businesses as well, including the ElDorado Motor Corp., National Coach, Champion Bus, Heartland and Goshen Coach companies.
