I have a 2004 2500 Suburban with the tan interior, RPO codes 521 and 522, and I want to purchase the cargo cover/shade for it. The local stealership says the part is discontinued and unavailable to purchase. I looked on GMPARTSDIRECT and eBay and all I could find where grey ones for purchase. Does anyone know the part number for the tan one or does anyone have one they would be willing to part with?
