Ranging from 15 to 35 feet in length and towed by means of a bumper or frame-mounted hitch attached to the rear of a towing vehicle, travel trailers can be disconnected and left at the RV park while the tow vehicle is used for short trips. The best-known is the iconic Airstream, now owned by Thor Industries and built in Jackson Center, Ohio. Of the 400 RV manufacturers in business when Airstream started in 1936, it was the only one to survive the Depression. In more recent times, it has been nicknamed the "Silver Bullet" and adopted by Hollywood celebrities like Brad Pitt and Tom Hanks.
