If you've ever driven on Interstate-75 near Saginaw and Bay City, MI, you know part of the International RV World Story. Do you remember the tail lights illuminating an RV sales lot at night? That's International RV World. The running lights are only small pieces of the story, though. The bigger part of the story is family. The story starts in 1937 when company founder Big Jim Harvey was born in a 1937 Schultz trailer. Trailers were a big part of Jim's life. Jim grew up living in RVs and spent his childhood working at his father's trailer and mobile home businesses. In 1957, Jim went out on his own and became very successful in the RV industry.
