A monster truck built from a dually pickup is due to appear in Grand Theft Auto VI, seen driving at the Thrillbilly Mud Club in the first trailer and in official artwork of Ambrosia. It appears to be based on the Ford Super Duty, riding lifted suspension and huge off-road tires like those of the Liberator and Marshall while sharing cab details with the Caracara 4x4.
