Titanic, The - Dirty, rusty yet functioning mobile RV home, parked outside of San Francisco Memorial Hospital on the medical drama TRAPPER JOHN, MD/CBS/1979-86. The Titanic belonged to Dr. George Alonzo "Gonzo" Gates (Gregory Harrison), an on-call resident surgeon, who often spent time on the roof relaxing in lounge chairs and drinking beverages. This mobile home, like the ocean bound Titanic had one thing in common: they both were disasters.
