Cab configuration
Compare sleeper size, storage, bunk climate, wheelbase and weight for the time spent away.
SPECIFICATION PLANNING
Semi Truck Spec Planner
Turn your intended work into a focused list of specifications to investigate. This tool does not engineer or recommend a specific truck.SPECIFICATIONS TO INVESTIGATE
Your research brief
Wheelbase & fifth wheel
Check trailer clearance, manoeuvrability, fuel and equipment packaging, fifth-wheel travel and axle loading for dry van work.
Engine & aftertreatment
Research the installed engine generation, rating, hours, idle time, duty cycle and emissions history. 160,000 annual kilometres makes documented maintenance and operating-cost assumptions especially relevant.
Transmission & rear axle ratio
Match exact transmission ratios and axle gearing with tire revolutions, mixed terrain, operating speed and driver or fleet requirements.
Axles, suspension & cooling
Confirm axle ratings, suspension, cooling and fuel capacity against the actual load and routes.
Fuel capacity & operating cost
Balance route range and fuelling access against tare weight, annual kilometres and realistic L/100 km assumptions.
Confirm final suitability. Verify the actual truck build, intended work, legal requirements and professional/operator requirements before purchase.
Method & interpretation
Method: The planner turns the buyer-entered operation, trailer, terrain, sleeper need, exposure and annual kilometres into specification questions and model families worth researching. It does not score or engineer a build.
Example: Selecting vocational work, a dump application and mountainous terrain emphasizes component ratings, frame, suspension, cooling, PTO provision and low-speed gearing rather than an aerodynamic highway shortlist.
Interpretation: Use the brief to collect build sheets, labels and application-specific professional advice. A listed model is a research starting point, not a compatibility or purchase recommendation.
