APU Coverage for Commercial Trucks: What It Means and Why It Matters
When you’re operating a commercial truck, every component that keeps your vehicle running efficiently matters. One often overlooked but extremely valuable system is the APU, or Auxiliary Power Unit. For owner-operators and fleet managers, protecting this system can mean the difference between staying productive on the road or dealing with unexpected downtime.
That’s why APU optional coverage through Total360™ is an important consideration for trucks operating long hours or traveling across the country.
What is an APU in Trucking?
An APU (Auxiliary Power Unit) is a small engine installed on a commercial truck that provides power to systems such as:
• Heating and air conditioning
• Battery charging
• Cab electronics
• Engine block heaters
Instead of idling the main engine during rest periods, the APU allows drivers to maintain comfort and power inside the cab while saving fuel and reducing engine wear.
Many fleets rely on APUs to help meet anti-idling regulations while improving fuel efficiency and reducing maintenance costs.
According to the U.S. Department of Energy, auxiliary power units help reduce unnecessary engine idling and fuel consumption in heavy-duty vehicles.
Why APU Protection Matters
While APUs improve efficiency, they are still mechanical systems with many moving parts. Like any engine component, they can experience wear and mechanical failure.
Without coverage, repairs can be costly and may leave a truck temporarily out of service.
That’s why Total360™ offers optional APU coverage to help protect critical internal engine components.
