Truck bed extension/ramp

A combination bed extension/ramp structure for attachment to a sleeve-hitch of a truck having a bed, the structure comprising:

• a non-revolving-hitch attachment member;
• a rear panel pivotally connected to the non-revolving-hitch attachment member to pivot around a first substantially horizontal axis from a first substantially upright position to a second position, wherein the rear panel is acting as a ramp between a rear panel-ground contact point and the plane of the non-revolving-hitch attachment member;
• a front substantially rectangular panel pivotally connected to the rear panel at an intermediate point whereby when the rear panel is in the first position, the front panel is positioned substantially horizontal and at a level suitable to form an extension to said bed;
• whereby when the rear panel pivots from the first position to the second position, the front panel automatically pivots relative to the rear panel around a second substantially horizontal axis and moves from the horizontal position to an inclined position that complements the inclination of the rear panel in the second position;
• and
• whereby the structure can be converted between a bed extension mode and a ramp mode while attached to said truck.
