Also in 1991 Thor acquired Dutchmen Manufacturing, now one of the leading brands of travel trailers and fifth wheels. Four Winds International, manufacturer of Class A and Class C motorhomes, was acquired in 1992. Komfort Corporation, builder of trailers and fifth wheels, became part of the growing Thor family in 1995. 1996 saw the start-up of Thor California, which became one of the most successful RV start-ups.
http://www.thorindustries.com/corp/component/content/I have a 2007 Komfort Kampsite and a sticker on the outside says manufactured by Thor. I know you are referring to a 2011 model, but per Thor's website, looks like those acquisitions were in place for some time.
