Filmmaker and professional storm chaser Sean Casey was set to start work on the sequel to his IMAX film "Tornado Alley" when a chance meeting with a Cummins representative led to a partnership to prepare the Tornado Intercept Vehicle known as TIV2 for the adventure. Cummins took TIV 2 in for repairs during the month of April 2012. This video provides an overview of TIV 2, "The Dog House," and Sean's work on his movie and a National Science Foundation project to probe the inner workings of tornadoes.
