(Nov. 7, 2011) -- Thor Motor Coach (TMC) is recalling 106 model year 2011-2012 Tuscany, Astoria and Avanti RVs equipped with a Cummins ISX or ISL diesel engine. The V-band clamp assembly used to connect the inlet and outlet cone sections to the diesel oxidation catalyst include a T-bolt which can fracture and fail when subjected to stress or load.
