It is a 1989 GMC R3500 crew cab dually. My father and I built this truck full custom. One of kind! It went from bone stock to wild. Made the bed, custom from and center section, full air ride lays frame on 24″ freight liner semi wheels, custom interior, digital dash, custom built center console from front to rear, 24 speaker, 3 amps, semi hitch, 454bbc full roller with direct port injection, and so much more.
