I call it a Sunvisor, it serves to protect you when the Sun is above, also when it snows, rains wind etc. One of my best investments, will last a good 12 plus years, with Uv hitting strong on it My 2002 had one, my 97 had one. They look easy to install, they are easy to install. I just make it look easy that is all. Oh yes some one asked about steps. they are very useful. so not sure why forum people love to complain about things.
