How the night shift runs it

Maintenance is where fleets bleed quietly

Every owner I've sat with can tell me the cost of a new tractor down to the dollar. Ask them what last quarter's maintenance ran across the fleet and the answer is usually a shrug followed by "a lot."

That's the quiet bleed. A $400 repair here, a $1,200 PM interval there, a tire job that should've been rotated 10,000 miles ago. None of it shocks you on the day. Stacked across a year and 12 trucks, it's 6 figures.

DOCKEX maintenance turns the whole pipeline into a kanban board with receipts attached. Every wrench turn ties back to the vehicle. Every dollar lands on a cost report. Every part comes out of inventory and goes onto a work order automatically.

The work order board

Three lanes: Open, In Progress, Complete. New work order drops into Open with a vehicle, a description, and an estimated cost. Drag it right when a mechanic picks it up. Drag again when it's done.

Each card holds the mechanic, time logged, parts pulled, and running total. Click into the card for the full audit trail (which is what your DOT auditor or your insurance adjuster will ask for, in that order).

The board is the operational view. The vehicle record is the historical view. Same data, two angles.

Predictive maintenance, explained honestly

Half the "AI maintenance" pitches in this industry are vibes. I'll be specific about what DOCKEX actually does (so you can pressure-test it before you trust it).

For each vehicle, DOCKEX watches real signals: MPG drift over a rolling 30-day window, repeat-repair patterns (the same component touched twice in 6 months), cost-per-mile trend, and — once you connect a Samsara, Motive, or Geotab integration — live engine fault codes off the ECM. When a signal crosses threshold, the vehicle gets flagged with the signal that fired. It's rule-based, not a black-box score — just the receipt.

You see exactly why the flag fired. If the signal looks right, you schedule the PM early. If it looks wrong, you dismiss it. Service-due itself runs by mileage and time, so the routine PMs land on schedule regardless. That's the whole mechanic.

Parts, tires, and the small stuff that compounds

Parts inventory tracks stock counts, reorder points, vendor pricing, and per-vehicle consumption. When a mechanic pulls an air filter for a PM, the count ticks down and the cost lands on the work order. Reorder triggers fire when stock hits the threshold.

Tire health is its own quiet bleed. DOCKEX tracks each tire by position (steer left, steer right, drive 1L, drive 1R, drive 2L, drive 2R, all the way back), logs tread depth and pressure readings, and flags rotations and replacements based on wear patterns.

For small Oklahoma fleets specifically, the maintenance stack plays directly into the day-to-day chaos. The small-fleet playbook walks through how to set up service programs, work order routing, and PM intervals so the maintenance side stops eating Sundays.
