With no device at all
Your own entries and the documents you photograph are the record. An owner records an oil service, keeps the shop receipt with that truck, and finds it when the buyer, the auditor or the next mechanic asks.

Keep the truck ready.
A truck out of service does not earn. Neither does one that passes inspection but nobody can prove when the brakes were last done.
Keep the repair history with the truck.
Record the work, keep the details, attach the receipt where permitted, review the history, plan the next service. RoadLink is a planned device that can add readings to the same history; it is never required.
An oil service, a brake job, a tire swap: the truck, the date, what was done and the odometer.
Building nowThe shop, the parts, the cost and a note in your own words, on the truck's own record.
Building nowPhotograph the invoice when you pay it. It stays with the owner's records; a driver with service-note access never sees the dollars.
Building nowOne timeline per truck, by VIN, that survives a driver change. Readings and reported conditions can join it later with RoadLink.
PlannedMileage, hours and date rules you set, plus registration and inspection dates surfaced before they lapse.
Planned
With RoadLink, later
Available engine hours, distance and reported conditions can join the same history, so a later condition can be read against the earlier repair. The device reports; you and your documents still say what was actually done.
One history per truck, by VIN.
Service, parts, tires, the shop that did it and what it cost. Tied to the specific truck, so it survives a driver change and follows the unit rather than the memory.
The receipt is part of the record.
Photograph the invoice when you pay it. The maintenance entry and the paper that backs it stay together, which is the only version worth anything later.
Dates that cost money are dates you see coming.
Registration, inspection, the annual. The plan is to surface them before they lapse rather than after a roadside stop makes it somebody else's decision.
Maintenance is part of cost per mile.
What you spend keeping the truck running belongs in what the truck costs to run. It flows into the same numbers as fuel and the payment.
What is in it, and where each part stands.

Engine readings on the same history
In designWith the planned RoadLink device: engine hours, distance and reported conditions beside the repairs you recorded. A reported condition is not a diagnosis.
Keep the unit earning.
The pilot is how this gets built with real trucks behind it. Leave an email and we will write when there is something to try.
