(CNN) – After selling his Illinois gourmet food store and moving to Austin six years ago, Chris Miller was anxious to open another food-related business. So he became an early pioneer of one of food world’s hottest trends: mobile food trucks. Miller’s hot-dog trailer transplants a Chicago classic down south. “I manage the trailer myself with a small crew, keep a close relationship with all my customers — many I know by first name –and put out a quality product that people really seem to enjoy,” Miller says.
