One man is dead and another severely burned in an RV fire in Phoenix. Phoenix Fire Department officials say a 29-year-old man injured in Tuesday afternoon's fire is hospitalized with second and third-degree burns over most of his body. The names of the two men have not been released but fire officials believe the victims are an uncle and his nephew. The RV had been parked in a driveway outside a home. The two men were taking the motor home for a test run after not using it for a long time. Fire officials say a problem occurred in the engine, it caught fire and the entire front of the vehicle was gutted by flames.
