Give your RV extra protection with our SideOut Kover III. Our RV slide toppers operate automatically with your slide out. The integrated wind-deflector prevents billowing and provides fabric protection for when you travel. The concealed, built in cradle support prevents the roller assembly from sagging to enhance the unified, sleek, modern look for your RV. All mounting screws are completely covered and concealed to finish off the clean look. The roller tube, bracket assemblies, and wind deflector are all made of extruded Aluminum for longer lasting durability. The deflector and covered model are available in standard white or black, with matching vinyl, brackets, and end caps.
