Of all the trucks on the road the Peterbilt model 320 is second to none. With innovative standard features, unparalleled design flexibility and cab improvements that maximize driver comfort the low cab forward 320 is well suited for the harsh conditions of the concrete pumping industry. With the quietest engine ever to power a concrete pump truck, the new Cummins is smooth, powerful and silent with fuel economy that is clearly superior in it’s class. From it’s super-strong chassis to it’s outstanding maneuverability, the 320 is pure Peterbilt. Rugged. Reliable.
