Thor RV Company is a massive RV company with many, many brands of RVs. However, many people will START with searching for Thor Travel Trailers.
By massive, I mean that Thor sold in 2018 over $8B of RVs and maybe a few other things. They have 17,000 employees. Compare that to Forest River who employs around 10,000.
Their brands are Dutchmen, the iconic Airstream, KZ, Crossroads, Heartland, Jayco, and many more. These brands are MORE like manufacturing facilities than necessarily brands. Thor does a very good job of buying some of the most iconic brands in the RV industry.
