Gray truck on a gray day, but a bright driving experience: 2021 Model 567 dump is ready to roll at Ohio Peterbilt. It has very low miles, the right specs for northeastern Ohio, and looks and performs like new. That makes it a compelling argument for buying “used.”

A trio of single-rear-axle plow trucks sporting green and amber strobes cleans a stretch of Ohio highway after a storm has passed. Green lights are used only on snowplows, differentiating them from other road-maintenance equipment with amber-only lights.

More than half of all heavy trucks now in use are more than 10 years old, according to industry estimates, so their diesels lack pollution controls used in modern trucks. Operators keep the old, reliable vehicles because they can’t or won’t spend money on expensive new equipment.

Model 589 daycab tractor in “legendary” red with a black band looks handsome and purposeful, but closely resembles previous models. That is exactly what customers said they wanted and what Peterbilt designers gave them. The main change is the 2.1-meter-wide aluminum cab that’s 8 inches broader than the cabin on the 389, which now is out of production. Like older “Petercars,” the 589 can be outfitted for highway and on/off-road vocational duties.
