04 / MODELS, YEARS & CHANGES
One badge.
Different reference points.
Publication dates and launch milestones do not establish continuous model-year ranges. Match the VIN, production date and equipment era.
N13 and ISX15 reference
This edition identifies N13 and ISX15 options; it does not describe every earlier ProStar powertrain.
International ProStar sleeper · TAD11035 · March 2016 ↗Inspection and build evidence
Confirm N13 versus ISX15 and emissions year. Review aftertreatment, cab mounts, chassis fairing repairs, cooling system and transmission service.
- VIN-linked factory build record and production date
- Engine and transmission identification plates
- Axle ratings, tyre ratings and fifth-wheel installation
- Physical measurements of the individual tractor
05 / PUTTING IT TO WORK
Match the trailer to the whole truck.
Compare the tractor’s actual axle, tyre, coupling and combination limits with the intended trailer. Sleeper length, tank packaging and fifth-wheel position affect clearance; model names do not establish payload.
HIGHWAYTRAILERS.CA
Flatbed
Start with deck length, load placement, axle distribution and cab-to-trailer clearance.
Read the guide HIGHWAYTRAILERS.CAStep deck
Compare deck height, gooseneck geometry and the loaded combination’s height.
Read the guide HIGHWAYTRAILERS.CARGN / equipment hauling
Check neck compatibility, fifth-wheel loading, wet-kit requirements and the complete axle layout.
Read the guide HIGHWAYTRAILERS.CAHow trailer capacity works
Review the tractor, coupling, trailer, tyres and load as one combination.
Read the guidePulling a trailer
Confirm build-specific combination, axle, tyre and coupling ratings, kingpin and service connections, clearance and actual axle weights. GVW is the loaded truck; GCW is the loaded combination. Neither is trailer payload.
Moving the tractor as cargo
Give the carrier measured length, exterior and mirror widths, height, ground clearance and transport weight. Assess deck access, breakover, loaded height and securement together.
Deck height & loaded height ↗There is no single “ProStar towing capacity”.
The model badge, artwork and catalogue option selectors cannot rate an individual combination. Obtain the actual build limits and scale weights.

Reference-specific evidence needed
- Verify exterior body width and mirror width independently, plus overall length, accessory height and fifth-wheel height.
- Production-year boundaries and undocumented earlier variants need their own dated factory sources.
- Confirm emissions equipment, installed powertrain and axle ratios from the individual build.
