Mobile Tornado was created in 1999.
You should not be in a mobile home if there is a tornado coming. Mobile homes are very susceptible to tornado damage and should be abandoned for sturdier shelter during a tornado warning.
Mobile homes are very easy to be destroyed in severe weather like tornado. Among all people killed in tornado between 2000 to 2008, nearly half were killed in mobile homes. They can be easily destroyed by a comparitively weak tornado.
The short answer is: you can't. A tornado will probably destroy even a tied-down mobile home, so if a tornado is coming toward your mobile home, the only thing to do is run for it.
