We tested a truckman who will spend most of his time in quarries and construction sites. We drove the Renault K 520 8 x 4, which spoils us with two locks of differential, and also offers the Offroad program, which even makes it easier to drive on the toughest climbs. The K 520 also offers two cameras, in addition to the rear, it also has a side camera, which makes it easier to maneuver
