Abstract: The base structure for a truck bed extension and ramp system has a horizontal U-shaped planar frame and dimensions for forming a margin over a tailgate of a pickup truck. A pair of posts extend vertically from the ends of the U-shaped frame. A tailgate-latch coupler is movably mounted on each post. This tailgate-latch coupler has dimensions for attachment to a tailgate latch member of a pickup truck. Each tailgate-latch coupler is movable up and down along the post and is connected to the tailgate latch member of a pickup truck and to retain the base structure to the truck box.
