The picture above is of a 2007 Chevrolet Silverado 1500 HD Extended Cab (whoo..what a name!). This is the first image of the GMT-900 truck interior. Notice that it follows close in layout to the GMT-800 trucks, which is ergonomically a great design. This image also busts all the myths that the Silverado interior would be just like the Tahoe's. It is believed that the truck pictured is of a model that will be one level above base.
