Based in Elkhart, Indiana, Thor Industries manufactures Class A, Class B, and Class C motor homes along with travel trailers and fifth-wheel towables across about 35 brands. Through the acquisition of Erwin Hymer in 2019, the company expanded its geographic footprint and now produces various motorized and towable recreational vehicles for Europe, including motor caravans, camper vans, urban vehicles, caravans, and other RV-related products and services. The company has also begun generating revenue through aftermarket component parts via the acquisition of Airxcel in 2021; however, this is still a nascent part of the business as it accounts for less than 10% of fiscal 2025 total sales. In fiscal 2025, the company wholesaled 181,388 units and generated $9.6 billion in revenue.
