The GM-5000 is a 5,000-liter vacuum truck (also called a vac truck, hydrovac truck, or pumper truck) mounted on a minimum 11,000kg GVW chassis, for municipal and industrial liquid waste removal — adding hydraulic door locking on top of the hydraulic tipping and door opening carried over from the GM-3000.

A 390 cum/hr vacuum pump, driven off the vehicle's gearbox-fitted PTO, generates high vacuum in the tank to siphon effluent, liquids, and sludge out of sewer lines, septic tanks, lift stations, and catch basins through a 3" x 15m suction hose. A sludge stirring arrangement uses high-velocity air to convert solid silt into a liquid or semi-liquid slurry the pump can draw up, and a blow-back system can then discharge just the water content of the tank under pressure, so the load carries away the sludge without hauling unwanted water weight. Once full, the tank tilts hydraulically and the rear door opens and locks hydraulically at the disposal site. Primary and secondary ball-float shut-offs, plus a basket strainer, protect the pump from solids and tank overflow.
Available hydraulic features vary across the GM-series by tank size. On the GM-5000:
A hydraulically operated suction hose reel becomes available on the GM-8000.
