Before you buy a Ram or an F-250 — will it stay on your car licence, and what can it actually carry?
American full-size trucks live or die on two numbers most buyers never check: the 4,500 kg GVM licence line and real-world payload once the build, fuel, water and people are on board.
Pick a truck, set your licence class, choose your build and load. We'll show you the payload left, the GCM headroom when towing, and — clearly — whether it keeps you on a regular car licence or needs a Light Rigid truck licence.
What licence will you be driving on?
The 4,500 kg GVM line is the car-vs-truck licence cliff — it's federal (HVNL), the same in every state. Filter the whole tool by which side of it you want to stay on.
NB1 / NB2 is not a licence class. NB1 = GVM up to 3.5 t, NB2 = GVM 3.5–4.5 t. Both are an ADR registration category set federally and both are drivable on a car licence — the only line that changes your licence is 4,500 kg GVM. Always confirm the exact build's compliance plate and check upgrade rules with your state transport authority.

Select your truck
What's on the back of your truck?
The single biggest payload decision. The same touring gear in three different builds leaves very different payload behind.
Are you towing?
People, water and fuel
Touring accessories
Tick what's fitted. Default weights are typical figures — override them to match your actual setup.
This calculator is an estimate. Confirm actual loaded weights at a weighbridge, and verify licence class, ADR category and any GVM-upgrade rules with your state or territory transport authority — these can change and vary by jurisdiction. American trucks sold here are remanufactured to right-hand drive by a converter; specs, availability and pricing depend on the converter and model year. Figures marked with a flag are best-available estimates. Rainger Supply Co does not provide engineering or compliance certification through this calculator.
Why payload disappears faster than people expect
Four things to know before you commit to a full-size American truck build.
Payload includes everything
Passengers, water, fuel above the test condition, food, fridge, batteries, tray, canopy, drawers, tools, recovery gear — every kilo comes out of the same allowance.
Tow rating isn't GCM
A big braked-tow number doesn't mean you can tow it and carry a full load. GCM caps the combined total — and on heavy trucks it bites sooner than the brochure suggests.
SRW vs DRW changes the math
Dual rear wheels lift axle ratings, GVM, GCM and payload — but add width and weight, and often push GVM over the 4.5 t licence line. They are genuinely different vehicles.
The 4.5 t licence cliff
At 4,501 kg GVM you leave car-licence territory and need a Light Rigid (LR) truck licence. It's federal — same in every state. Many HD trucks (and some GVM upgrades) cross it.

GVM upgrades by state & territory
What's federal vs what varies locally. Pre-registration upgrades (second-stage manufacture) are broadly national; post-registration upgrades are where states diverge. The 4.5 t licence line itself is federal.
| State / territory | Pre-rego GVM upgrade (2nd-stage manufacture) |
Post-rego GVM upgrade (in-service) |
4.5 t licence note |
|---|
General guidance only — GVM-upgrade and second-stage-manufacture rules change and are administered per jurisdiction. Confirm the current position with the relevant state or territory transport authority and your certifying engineer before purchase. Crossing 4,500 kg GVM (by spec or by upgrade) moves the vehicle to a Light Rigid (LR) truck licence nationally.
Why the 4.5t line is bigger than a licence
Crossing 4,500 kg GVM doesn't just change your licence — it changes the rules you drive under, what the truck costs to run, and who in the family can legally get behind the wheel. Most of this is set per state, so check your own state's current rules.
Zero BAC, not 0.05
In some states, driving a vehicle over 4.5t GVM puts you under heavy-vehicle rules — a zero (0.00) BAC limit instead of the usual 0.05. Victoria applies zero-BAC to all heavy-vehicle drivers over 4.5t (since 1 April 2021); Queensland applies 0.00 over 4.5t as well. NSW is stricter than 0.05 (a special low limit) — confirm the exact figure. Under 4.5t you keep the normal 0.05.
A truck licence — per person
The Light Rigid (LR) licence is per driver: roughly $1,000–$1,300 each, you must have held a car licence 12+ months, and it needs a heavy-vehicle knowledge test plus a practical assessment. Two partners both driving = two upgrades (~$2,000–$2,600). Under 4.5t, everyone drives it on a car licence.
The emergency problem
If only one of you holds the LR licence and they're the one who's injured or can't drive, no one else can legally move the truck. Under 4.5t, anyone with a car licence can take the wheel.
More to keep on the road
Registration is weight-based. In NSW a private vehicle of 4,325–4,500 kg tare runs about $1,481/yr in vehicle tax vs ~$270 for a light car (from 1 July 2025); WA charges about $28.64 per 100 kg of tare. A near-4.5t truck can cost ~$1,000+/yr more in rego alone — before higher CTP and insurance (value + mass), plus the one-off LR licence.
Licence, BAC and registration rules vary by state and change — confirm with your state or territory transport authority.

Who actually converts American trucks in Australia
We don't convert trucks — these companies do. Because there's no US factory warranty once a truck is remanufactured to right-hand drive, who did the conversion is what your warranty, parts, insurance and resale hang on. When a converter collapses, that warranty can stop — as happened when a major Australian converter group entered receivership in 2026. Here's the landscape — a genuine reference, not a referral.
Walkinshaw Group
Factory-backed remanufacture behind Ram Trucks Australia and Chevrolet Silverado (GMSV) — the only manufacturer-backed-warranty path.
VDC / Harrison F-Trucks
Vehicle Development Corporation — a long-running F-Series RHD converter; supplies the Harrison F-Trucks retail brand (Melton, VIC).
Performax International
Importer, converter and retailer since 1989 (Gympie, QLD) — Ford, Chevrolet, GMC and Toyota.
Autogroup International
Right-hand-drive converter for 30+ years (Pakenham, VIC) — Ford, RAM and GMC.
American Trucks Australia
Right-hand-drive Ford, RAM and GMC imports and retail (Gold Coast, QLD).
US Autos Sydney / Southern Classic
A long-running Sydney right-hand-drive converter.
The Southern Classic Trucks brand has folded into Melbourne City Auto Group.
Whatever you build it on, payload is the enemy. A canopy-camper setup (around 120 kg) leaves far more usable payload than a 300–450 kg tray + alloy canopy — designed for Australian conditions. See exactly how much your build leaves you.
