The 12 Traits of Highly Profitable Trucking Companies: Maintenance Excellence – Digging Out of the Deepest, Darkest Hole in Trucking

Maintenance excellence requires standardized cost data, documented repair stances, disciplined PM intervals, inventory control, and executive attention.

Maintenance becomes a major competitive advantage when carriers measure its full cost, document the reasons behind repair practices, enforce preventive-maintenance intervals, manage parts as depreciating inventory, and give maintenance leadership executive authority.

How the Role-Model Traits Were Identified

KSMTA began with more than 50 truckload carriers, assigned observed traits to each, and counted which practices appeared most often. Company culture and operating knowledge narrowed the group to four role-model carriers.

Although the traits were not presented in a strict sequence, KSMTA viewed transparency as foundational, followed by network discipline and maintenance excellence.

The Maintenance Cost Gap

Maintenance was described as the deepest, darkest hole of lost profit in trucking.

Holding tractor age constant, dry-van maintenance—including parts, labor, and shop overhead—ranged from approximately $0.14 to nearly $0.40 per total mile among benchmark participants.

Technical knowledge in a strong shop leader matters, but the organization should convert that knowledge into documented strategy and processes so performance does not depend permanently on one all-star employee.

Document the Operation

Maintenance is highly dependent on documentation. As sensors and connected equipment grow, carriers also need proven maintenance software capable of supporting repair history, codes, parts, and performance analysis.

Establish a Cost Baseline

General-ledger accounts should map cleanly to maintenance software and repair-order categories.

Recommended practices include:

  • Create a separate maintenance labor and overhead department, including its share of facility cost.
  • Separate owner-operator repair expense and revenue from company-equipment maintenance.
  • Distinguish tractor repair, trailer repair, and tires, including material and labor.
  • Maintain accounts for unallocated shop labor and overhead.
  • Create dedicated warranty repair and OEM credit accounts.
  • Use the same GL structure at every shop location for internal comparison of proficiency, efficiency, and productivity.

The maintenance application can provide deeper equipment-level analysis by age, make, model, and specification without requiring excessive general-ledger complexity.

Establish Repair Stances

A stance resembles a standard operating procedure but goes further by explaining why the company follows the guideline.

Preventive Maintenance

Preventive maintenance should have the highest priority. World-class fleets work toward a PM-to-PM philosophy: complete comprehensive inspections and address foreseeable maintenance needs while the equipment is already in the shop, reducing unscheduled visits between services.

Detailed checklists and documented stances support that execution.

Cost Management

The carrier should decide when higher-quality parts and repairs justify a larger upfront cost and when a less expensive option is appropriate. The article uses recap versus virgin tires as an example.

Downtime Management

Stances should address backup equipment, rentals, and other methods for reducing the operating effect of a repair.

Set PM Intervals and Compliance Windows

Choose service intervals using industry guidance, dealers, and peers. Then define what counts as on time.

For a 30,000-mile tractor interval, the acceptable window might be 28,000 to 31,000 miles. Exception reports should identify units outside the window and assign accountability. A truck significantly beyond the limit may need to be placed out of service automatically.

Proximity Can Be a Maintenance Killer

A tractor being near the terminal is not, by itself, a reason to ignore the established interval and complete maintenance early. Appropriate windows should provide enough flexibility to wait until the correct time.

Repeated convenience exceptions reduce tractor productivity and shop productivity.

Maintenance Needs Executive Representation

A capable maintenance leader should have a seat at the executive table. That position demonstrates the function's importance and helps ensure it receives the resources needed to protect equipment availability and cost performance.

Be Relentless on Parts Inventory

Every part purchased for future use is a declining annuity. Its value begins falling when it arrives and may disappear quickly as fleet makes, models, and specifications change.

The parts-inventory module in the maintenance system should track turnover, obsolete inventory, and purchasing patterns. Disciplined inventory management is another necessary part of turning maintenance from an uncontrolled cost center into a source of stronger margin.

Frequently asked questions

How wide was the dry-van maintenance cost range?

Holding tractor age constant, all-in parts, labor, and shop overhead ranged from approximately $0.14 to nearly $0.40 per total mile.

What should maintenance general-ledger accounts separate?

The article recommends separating tractor and trailer repair, tires, shop labor and overhead, owner-operator repairs and revenue, and warranty work and credits, with consistent accounts by facility.

How is a repair stance different from an SOP?

A repair stance explains the reason and strategy behind a guideline, helping employees understand why the process exists and increasing compliance.

What example does the article give for an on-time PM window?

For a 30,000-mile service interval, a carrier might classify preventive maintenance completed between 28,000 and 31,000 miles as on time.
