Short and long BBC options
A dated factory brochure supplies 115.5 and 122.5 in references. Neither value is overall tractor length.

Planning to transport the truck?
Measure fixed exterior width and mirror width separately, plus overall length, the highest accessory, fifth-wheel height and actual transport weight. Interior bunk width is not exterior width.
03 / UNDER THE SKIN
Powertrain & chassis
Engine and emissions year require the build record. 2012 conventional · multiple vocational configurations. Read engine, gearbox and axle ratings together.
Numerical powertrain ratings need a dated configuration-specific source. Cummins, Caterpillar and PACCAR-era possibilities plus broad manual/automated choices vary dramatically by year; the component tags are decisive.
Documented cab options
- Day cab
- 38 in AeroCab
- 72 in AeroCab Aerodyne
- 72 in AeroCab FlatTop
- 86 in Studio Sleeper
Documented transmissions
Read the installed unit’s identification plate and build record.
The 2012 brochure offers two BBC lengths. It does not map every sleeper and engine to each hood; confirm the actual order.
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.
A broad vocational family
Day cabs and AeroCab sleepers appear in the catalogue. Heavy-haul, tanker and other equipment require their own frame, axle and coupling checks.
Kenworth T800 factory brochure · 2012 · dealer-hosted ↗Inspection and build evidence
Check resource-road wear, corrosion, steering and suspension mounts, driveline angles, double-frame condition and legality of later modifications.
- factory line-set or build sheet
- engine and transmission tags
- axle/suspension ratings
- PTO and body documentation
- frame-modification and repair records
05 / PUTTING IT TO WORK
Match the trailer to the whole truck.
Logging, oilfield, dump, heavy-haul and highway examples impose different frame, cooling, gearing and service histories.
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 “T800 towing capacity”.
The model badge, artwork and catalogue option selectors cannot rate an individual combination. Obtain the actual build limits and scale weights.
