The second-generation Bravado Bison is a crew-cab pickup truck due to appear in Grand Theft Auto VI. In the second trailer a silver one tows a jet-ski trailer along Interstate 97 and a red one briefly passes Lucia during her community service, and a police variant with a lightbar has also been noted. The truck appears to be based on the fifth-generation Ram pickup.
