"Thor achieved solid gains in revenue for the second quarter ending January 31, 2013 as the momentum of our RV products introduced in the fall continued at Louisville in late November. Indications from the early RV retail shows have been very positive, with increased traffic and higher sales levels, reflecting continued strength in our industry," said Peter B. Orthwein, Thor Chairman & CEO. "Despite the improvements in RV sales, the overall environment in the towables market remains very competitive, and elevated levels of incentives associated with orders placed at the fall Open House are reflected in our sales and our second-quarter operating results that we expect to report on March 7. In addition, the bus business continued to be characterized by aggressive competition during the second quarter," he added. Thor is the sole owner of operating subsidiaries that, combined, represent the world's largest manufacturer of recreational vehicles and is a major builder of commercial buses and ambulances.
