What maintenance does a V-Trail need?

Interval	Activity
Monthly	Visual inspection
Quarterly	Battery check; cooling and ventilation
Six-monthly	Solar cleaning; system health check
Annually	Firmware currency

Plus the trailer itself: tyres, bearings, brakes, coupling and lights on a road-registrable schedule, and the generator on its own service hours rather than on a calendar.

Two things that matter more than the schedule:

Keep the logbook. V-Trail is supplied with a maintenance schedule and logbook template. Abnormal findings should be reported promptly, a fault left running is a fault the warranty may not cover. On a fleet asset that moves between crews and sites, the logbook is the only continuity there is.

Track generator service by run hours, not by calendar. A unit that spends most of its deployments on solar accumulates generator hours slowly; one working a high-load site accumulates them fast. Calendar-based generator servicing over-services one and under-services the other.
