It’s hard to believe food trucks have only revved their foodie engines in the U.S. since 2008. In that relatively short window of time, they’ve become a culinary juggernaut. No longer a novelty in major metropolitan areas, food truck hubs are now common in mid- to small-size cities, too. The U.S. Chamber of Commerce found the food truck industry generated $2.7 billion in revenue in 2017 and has been growing on average at a rate of 7.9% every year.
