A tonneau cover includes a sheet of material. The sheet of material may have a first section and a second section, with a hitch aperture to receive a pin box of a fifth wheel trailer. The hitch receiver may be located under the hitch aperture when the tonneau cover is positioned on the truck. The first and second sections may couple to the truck bed via a first and second bracket. After the first and second sections are in position, a trailer may be attached to the truck while the truck bed is covered.
