Thor owns 9 different brand names comprising of 69 different models from MH's to travel trailers. One would think they are the most experienced of anyone in manufacturing these products. Yet they consistently put out junk. They are very good at aesthetics but fail in substance. They should be the leaders in manufacturing quality and expertise.
It's all about cornering the market for them. When you buy out your competition you control the profits. Many good manufactures brand names have suffered because of the Thor acquisition of them. What they are the best at is making money and putting others out of business.
