Company history
Thor Motor Coach was founded in 1987 and has grown into the largest producer of self-propelled RVs in North America. It sits inside Thor Industries, the group that also owns Forest River and Airstream, which is why its coaches carry a wide spread of sub-brands and model names.
The company's approach has been volume and range: a great many floorplans across Class A and Class C, at a great many price points, sold through a large dealer network. That breadth is the point, and it is also what makes the brand names inside the catalogue confusing to a first-time buyer.
Because the group owns several manufacturers, two coaches that look similar on a dealer lot may be built in different plants with different component suppliers. The builders' plate on the wall is the authority, not the brand name on the side.
