Mitch Lacher, Managing Member & Fleet Manager:
“We rely on Green APUs across our fleet because of the dependable diesel engine and the easy access to affordable parts. I can pick up belts, filters, and even alternators from local auto parts stores—no need to go through dealer networks or proprietary vendors.
The diesel APU performs reliably, even in sub-zero conditions. When our drivers return to their trucks, I know the engine will start, no matter how cold it gets. The unit keeps the batteries charged consistently, eliminating the dead battery concerns we’ve had with electric APUs.”

They combine performance and looks — with chrome and polished finishes that enhance airflow and style. The exhaust kits and steps are made to bolt on clean, and they’re as sharp as they are durable.
Yes. The step surfaces are wide and built with anti-slip designs that hold up in rain, snow, and mud — no need to sacrifice function for style.
