This vehicle was designed as a pre-packaged food catering truck. It has a commercial grade warmer on board, non commercial refrigerator, ice chest, shelving, storage. It is a Fiat 500 with a battery/inverter built in. You plug it in to 110V at night and the warmer runs when the car is running or on battery. PERFECT for catering. The box on back does have a shelf that folds down for serving. Add your own credit card Square and you're in business!
