foodtrucks-engine. Engine is trading from a Citroen Hy 1959 model. The van was bought in Orleans, near Paris, and was previously used as a fire service vehicle, hence the name. It was still in active service until 1995! The van is painted in fire engine red, complete with a blue flashing siren and fire helmets under the front seats. Engine sells handmade artisan smoked saursages, locally baked buns and insanely good toppings.
