Heavy vehicle guide
Truck & Prime Mover Buying Guide Australia
A prime mover must be assessed as part of a working combination, not in isolation. Freight profile, route, trailer, mass limits, driver needs and whole-of-life operating demands all shape a suitable specification.
Designed for: Owner-drivers, fleet managers, freight operators and logistics businesses.

Eligibility, approval and terms are not guaranteed.
Start with freight and route
Document typical freight, loading method, route gradients, urban access and time spent at highway speed. The intended trailer and combination determine many specification choices.
Payload planning must use applicable legal mass limits and the actual tare of the completed combination, not a generic brochure assumption.
Driveline and cab specification
Engine, transmission, axle ratios, braking systems and fuel capacity should suit the duty cycle. Compare manufacturer guidance and operational records for similar work rather than pursuing output in isolation.
Cab configuration should account for shift length, visibility, fatigue controls, sleeper needs and safe access.
Used-truck due diligence
Check identifiers, ownership, service and repair records, odometer evidence and any modification approvals. A competent inspection should cover chassis, driveline, emissions equipment, brakes, suspension, tyres, electrical systems and coupling equipment.
Confirm whether the proposed vehicle and combination can lawfully access the routes required.
Accreditation and compliance planning
Heavy vehicle operators and drivers have duties under the Heavy Vehicle National Law where it applies. Maintenance, fatigue, loading and speed processes should be considered before adding a vehicle.
Regulatory requirements vary with the vehicle, operation and jurisdiction; use NHVR and relevant state or territory guidance.
Selection considerations
- Freight type, payload and loading method
- Trailer, axle and coupling compatibility
- Route access, gradients and urban constraints
- Driveline and braking suitability
- Cab ergonomics and fatigue controls
- Maintenance network, records and modification approvals

Frequently asked questions
How do I choose a prime mover specification?
Begin with the freight, trailer, route and legal combination requirements, then compare manufacturer specifications and advice for that duty cycle.
What records matter for a used truck?
Verify identity, ownership, service and repair history, odometer evidence, inspection results and approvals for relevant modifications.
Can Asset Connect Australia arrange truck finance?
No. We are a referral platform. We can pass an enquiry to an appropriately licensed professional who independently assesses and discusses options.
