This info may be a little dated, but still quite relevant. I knew that Thor was a dominant player in the RV industry, I just didn't realize it was the top player.

"US demand for RVs is forecast to reach $16.6 billion in 2021. Rising disposable personal income levels will support gains. In addition, sales stand to benefit from population growth among the age cohorts most likely to buy RVs.
While the US RV industry features low barriers to entry, it is dominated by several large manufacturers. Market leaders benefit from the high-value nature of large, well-equipped RVs and are able to capitalize on their well-known brand names. Here are the three leading companies to watch in the RV industry:
Thor Industries
Thor is the leading supplier of RVs to the US market. The company’s sales met over a third of US demand in 2016. Thor’s products include conventional travel trailers; fifth wheels; truck and folding campers; and Class A, B, and C motorhomes. The company owns many well-known RV brands, including Airstream, CrossRoads, Cruiser RV, Dutchmen, Jayco, Starcraft, and Thor Motor Coach. In June 2016, Thor acquired Jayco, which included the Jayco, Starcraft, Highland Ridge, and Entegra Coach brands.
Forest River
Forest River, a subsidiary of Berkshire Hathaway, manufactures RVs as well as utility cargo trailers, buses, and pontoon boats. The company ranked as the second leading RV supplier to the US market in 2016.
Brands owned by Forest River include Coachmen, Dynamax, Forest River, Palomino, Prime Time, and Shasta.
Winnebago Industries
In 2016, Winnebago stood as the third largest supplier of RVs to the US market. The company's RV products include Class A, B, and C motorhomes; travel trailers; fifth wheels; folding camper trailers; and truck campers.
These products are primarily marketed under the Winnebago brand name. In October 2016, Winnebago announced it would be acquiring Grand Design RV, a manufacturer of towable RVs."
