Mike Delfino used his truck not only personal reasons, but also for his plumbing business. The truck was often used for sinister events, such as the kidnapping of Paul Young and the burial of the wrench used to kill Monique Polier. In Season 4, Mike hid his drug addiction from his wife Susan Delfino, but keeping his painkillers prescribed by his neighbour and attempted murderer, Orson Hodge in the glove compartment. The Truck's first appearance was Ah, But Underneath and last appeared in the Season four finale. The truck was replaced in Season 5.
