Used Mack Vacuum Trucks For Sale

Used Mack vacuum trucks are common in sewer cleaning, catch basin service, industrial cleanup, and combo jetter applications because the chassis is built for severe-duty work and repeated stop-and-go operation. Mack models such as the GU713 are frequently spec'd under vacuum bodies from VAC-CON and other upfitters, giving buyers a platform that can handle high PTO demand, heavy debris loads, and the weight of fresh water and spoil tanks. On the used market, the real value is often in the complete package: chassis condition, engine and transmission match, hours on the blower or pony motor, and the condition of the vacuum and water systems.

For most buyers, the body and vacuum system matter as much as the truck itself. Common specs in this category include debris bodies around 8 to 12 yards, fresh water capacity in the 1,000 to 1,500 gallon range, hydraulic hose reels, hydraulic dump bodies, and combination sewer jetting systems with high-pressure water pumps. Many used units are equipped with positive displacement blowers or multi-stage fan systems, and some run a separate pony motor to power the vacuum and jetting package. A combo unit can reduce fleet overlap by handling line jetting and vacuum recovery with one truck, but it also adds another layer of maintenance that should be checked closely.

The Mack side of the equation usually appeals to buyers looking for a rugged vocational chassis with good parts support and a reputation for stability under load. Engines such as the Mack MP7 are common in this class, often paired with automatic or automated manual transmissions that make municipal and utility work easier on operators. Wheelbase, axle ratings, and suspension setup should be reviewed against the installed vacuum body, especially if the truck will be used in tight urban environments or on routes with frequent full-load hauling. Tire size, frame condition, PTO setup, and hydraulic performance also deserve close attention because vacuum trucks live a hard life and small issues can become expensive quickly.

A used Mack vacuum truck is usually a better fit when uptime and chassis durability matter more than having the newest emissions package or controls. Ex-municipal units can be attractive because they may have documented service histories and lower mileage for their age, but buyers should still evaluate engine hours, blower hours, pump output, tank integrity, boom wear, hose reel condition, and signs of corrosion from wastewater service. If the truck is a jetter combo, confirm the water pump rating, pressure and flow, and whether the system still delivers the performance needed for the pipe sizes and debris loads you handle.
