Step-in Taco Trailer. This is a 17′ trailer, enough to have a mobile kitchen on wheels. It has everything you need to prepare and to sell tacos in the city. It is built from a solid frame made out of metal. In the inside, it is finished in stainless steel. There is enough storage space for all your utensils and because of its size the working area is great to accommodate up to 4 people inside.
