Abstract: A truck bed gap cover covers a bed gap between a truck bed and a bed gate, and can include a first end flushly attached to a bed floor of the truck bed; a second end that extends from the first end and towards the bed gate; an optional hinge cover; and a hinge portion, attached to and between the first and second ends, and that hinges between a secured position and an active position. When the bed gate is open, the hinge portion is in the active position with the gap cover extending from the truck bed and over the bed gap, and when the bed gate is closed, the hinge portion is in the secured position with the hinge portion hinging upwardly with the second end extending upwardly with the bed gate. The hinge portion can be disposed above and/or adjacent to the bed gap. The first and second portions can be formed of a rigid material.
