Most RVs have a rear bedroom window and you can't put a window awning over it because the ladder blocks the arms. The Carefree SunShade? fits directly over the window. SunShades? roll up for travel and roll down for camping. Features Black FullView? open weave fabric, extruded aluminum roller, die cast zinc brackets, and Black castings with a 55" vertical drop. Custom sizes and colors are also available. Two year warranty on parts, labor and freight. Ordering Instructions: Measure your window from outside of frame, add three inches and select the exact or next wider size. Be sure you have a flat, unobstructed area to install the size selected.
