Frequently Asked Questions

What is included in a fleet maintenance program?

Our programs include scheduled preventive maintenance, oil and filter service, brake and tire checks, DOT and PA inspections, diagnostics, and repair tracking, all built around your run schedule.

How does a preventive maintenance program save money?

Scheduled preventive maintenance catches small problems before they become roadside breakdowns, reduces downtime and towing costs, extends component life, and helps keep your trucks DOT compliant.

Do you handle DOT and PA state inspections?

Yes. As an authorized inspection station we perform PA state inspections and federal DOT inspections, and we document everything for your compliance records.

Can you maintain a mixed fleet of different truck brands?

Yes. We service Freightliner, Kenworth, Peterbilt, International, Mack, Western Star, and Volvo trucks, so mixed fleets can be maintained under one program.

Do you keep maintenance records for our fleet?

Yes. We track service history and inspection records for each unit, which makes audits, warranty claims, and resale documentation much easier.

How many trucks do I need to set up a fleet account?

We work with operations of all sizes, from a few trucks to large fleets. Call 717-865-2388 and we will build a program that fits your operation.

Do you offer mobile and after-hours fleet service?

Yes. We offer 24/7 mobile road service and emergency support across Central PA so a breakdown does not take a truck out of service for long.
