Abstract: A removable window cover system for recreational vehicles that has unique window cover clamps that are permanently secured to the inside surface of the vehicles window around its periphery. The window clamps have a horizontal base portion that has an inverted U-shaped spring portion extending upwardly from its rear edge and the spring clamp portion forms a cavity having a predetermined width. A sheet of opaque material and a sheet of partial light transmitting screen each have a shape similar to that of the window and they also have their own trim strip extending around their perimeter. These trim strips are detachably secured in the cavity of the window cover clamps. When complete privacy is desired, both sheets of material would be secured in the window cover clamps.
