A breakdown of the top chassis options for septic pump trucks in 2025 – and how to choose the right one for your business.
When you’re investing in a septic pump truck, the chassis is one of the most critical decisions you’ll make. It’s the foundation of your truck – affecting everything from payload capacity to driver comfort, fuel efficiency, and long-term reliability. In 2025, several manufacturers are offering updated models that are built to last in the demanding world of septic pumping.
Let’s break down the top contenders for 2025: Freightliner M2 106, International HV, Peterbilt 567, and the Kenworth T880.
1. Freightliner M2 106
Why it’s popular:
The Freightliner M2 106 continues to be one of the most widely used chassis in the septic industry – and for good reason. It’s known for its fuel efficiency, easy maintenance, and lower upfront cost.
Pros:

2. International HV Series
Why it’s popular:
International’s HV model is built specifically for severe-duty applications. Its robust design and customizable specs make it a strong contender for large-capacity or off-road pump trucks.
