Our front windshield cover mounts to the outside of the van using a nylon strap & durable poly buckle that passes through the interior a the top, and another strap w/buckle around the side mirrors. This multi-purpose piece works great as a sun shade, privacy guard, and even as a frost & light snow protector. #rbcomponents #rbadventurevans #sprintervan #sprintervanconversion #adventurevan #snow #sun #privacy
