THOR Industries is the world's largest manufacturer of recreational vehicles by revenue and unit volume, producing towable trailers (travel trailers and fifth-wheels) and motorized RVs (Class A, B, and C motorhomes) under leading brands including Airstream, Jayco, Keystone, and Tiffin Group, with additional substantial operations through its Erwin Hymer Group subsidiary in Europe. The company sells its products through approximately 2,400 independent dealerships in North America and 1,100 dealerships in Europe, using a build-to-order manufacturing model with distribution supported by third-party floor-plan financing arrangements. Revenue is generated through wholesale sales of completed vehicles and RV-related components such as windows, climate-control systems, and aluminum extrusions to both dealers and end consumers, competing on price, design, quality, and service against other RV manufacturers and used vehicle alternatives.
