Abstract: A vehicle for temporary support of intermodal cargo containers, especially a trailer for a tractor/trailer rig, has deployable locating pins placed centrally along the length of a chassis, for locating containers placed end-to-end. The locating pins center containers of different lengths relative to the chassis, which is long enough to accommodate the longest standard length of container or two short containers. The locating pins are resiliently mounted such that a long container or misplaced containers that are set down on the pins, cause the pins to be depressed into the chassis. Stop pins define an endpoint for an end of a container, and two resiliently mounted engagement pins on each side, are positioned for engaging the corner fittings of intermodal containers when abutted against the locating pins.
