On this episode of Road Gang Radio, host Jimmy Mac sits down with Kevin Lindsey, Manager of Technical Service for TravelCenters of America, for an in-depth conversation on truck maintenance, data-driven diagnostics, and keeping nearly 300 service locations operating consistently across the country.

Kevin breaks down what his role really looks like behind the scenes, how TA uses data analytics to identify nationwide and regional maintenance trends, and why aftertreatment systems continue to be one of the biggest challenges in trucking. The discussion also covers EPA regulations, troubleshooting modern emissions systems, and how TA works to ensure drivers receive the same clear maintenance message no matter where they stop.

The conversation wraps with practical advice for drivers heading into 2026, including the importance of DVIRs, scheduled maintenance, communication with service providers, and why getting to know your truck can save time, money, and downtime.

This episode of Maintenance Matters is packed with real-world insight for owner-operators, fleet drivers, and anyone involved in truck maintenance and operations.

Jimmy Mac sits down with Kevin Lindsey from TravelCenters of America for a clear look at air dryers and tank checks. Kevin explains why your air filter should be one of the first things you review during any inspection. He also walks through how modern engines react to changes in airflow and how that can lead to injector strain, drivetrain vibration, and higher repair costs.

Kevin breaks down how an air dryer handles moisture, heat, and contaminants. He explains why temperature levels matter and why the purge valve often shows normal residue. He also talks about the difference between a leak, a seep, and a weep, and why moisture around certain seals does not always signal a problem.

Jimmy and Kevin wrap up by moving into tank checks. They connect the steps that lead from filters to compressors to dryers to tanks, and how each step affects brake performance.
