I use the WeatherTech shades. They block out light and reflect the sun to keep the heat out of the cab. In the winter they can be reversed to help warm up then coach.
I have a set for the E450 for sale if you are interested. They cove the windshield and the drivers and passenger windows. When I moved to the Super C, I had to order new ones to fit the F-550 cab.
