Abstract
Abstract A mechanism for preventing removal of a ramp from its storage space beneath the floor of a truck body when the door for the truck body opening is latched closed. The ramp is insertable into and is removable from the ramp storage space through an opening beneath the truck body opening. The door latching mechanism includes a latch bolt movably mounted on the door and engagable with a catch pin in the truck body floor. The latch bolt carries a pawl which is engagable with a portion of the ramp to prevent removal of the ramp when the ramp is properly stored. The pawl also prevents the latch bolt from engaging the catch pin if the ramp is improperly stored.
