You want your own business. You have a passion for food. So operating a food truck might sound ideal. Less overhead than a restaurant. Few if any employees. You drive to where the customers are. How hard could it be? Well, pretty hard. "If you plan on owning and operating your food truck, you should expect workdays approximating 12 to 16 hours as you will be in charge of every part of the business," the National Food Truck Association says on its website.
