NOVELTY - Sting trailer (100) comprises front end-wall (110) at first standard trailer length from its rear end (102); false end-wall (120) at second standard trailer length from its rear end; and hidden compartment (115) located between front end-wall and false end-wall. The first and second standard trailer lengths are different lengths defined according to established industry-standard lengths.    USE - Sting trailer used as semi-trailer.    ADVANTAGE - The sting trailer design enables person to pass from cargo-carrying compartment on one side of false end-wall to hidden compartment on other side of false end-wall. The frames improve structural integrity of false end-wall so that false end-wall is less likely to be damaged in events that other equipments collide with it. Braces and frame enables false end-wall to distribute and absorb vibrations, thus making it more difficult to detect false nature of false end-wall by knocking.
