This is not a driving game or animation — it's a towing compliance simulator that models your real vehicle and caravan combination. See weight distribution, sway risk, towball load and legal compliance in one visual dashboard before you pack a single item.
This is not a driving simulator and does not rely on advertised tow ratings alone. Built for caravan owners who want to know if their setup is safe and legal — not for entertainment.

The tow simulator checks whether your car can tow your caravan by comparing your real-world weights against legal and manufacturer limits. It looks beyond advertised towing capacity and evaluates GVM, GCM, payload, and towball weight together. This shows whether your setup is safe and compliant, not just whether the engine can physically pull the load.
See exactly how weight is distributed across your caravan's floor plan. The simulator uses a bird's-eye view of your caravan with colour-coded loading zones (front, middle, rear) so you can see at a glance whether your load is balanced or dangerously rear-heavy.
When your towball percentage drops below the safe range or too much weight sits behind the axle, the simulator flags a SWAY RISK warning. Caravan sway is the leading cause of towing accidents in Australia — the simulator helps you prevent it before you leave the driveway.
See exactly how your towball weight is made up — the caravan's base towball spec plus the effect of your cargo placement. Moving a heavy item from the rear to the front of the caravan changes the towball load. The simulator shows this in real time.
A visual gauge showing how close your combined vehicle and caravan weight is to the GCM limit. Green means plenty of room, amber means approaching the limit, red means you've exceeded it. One glance tells you where you stand.
Add, move, and remove cargo items across your caravan's loading zones. Each zone has a weight total and the simulator recalculates everything instantly — towball percentage, sway risk, axle loads — as you make changes.
Bull bars, roof racks, tool boxes, long-range fuel tanks — the simulator loads your aftermarket accessories from your KamperHub garage and includes them in the weight calculations. No more guessing whether your accessories pushed you over the limit.
Towing capacity alone does not tell you if your car can legally tow a caravan. Most vehicles reach their payload or GVM limit before hitting maximum towing capacity. Passengers, accessories, fuel, and towball weight all count toward these limits, which is why many caravans are technically overweight despite being under the towing capacity figure.
The free weight calculator is perfect for a quick compliance check. The tow simulator is for owners who want to understand and optimise their loading — especially before long trips, after adding accessories, or when towing close to limits.
If your setup fails the tow simulation, it means one or more legal weight limits are exceeded. This can result in unsafe handling, increased braking distance, voided insurance, and fines if stopped by police. The simulation highlights exactly which limit is exceeded so you know what needs to change before towing.
Will your vehicle handle the caravan you're looking at? Enter the specs and see the full picture before you sign anything. Check GCM, towball load, and whether you'll have any payload left for gear.
You're packing for three weeks in the outback. Extra water, extra fuel, extra food. Will it all fit within your limits? The simulator shows you exactly how much room you have — and where to put it.
That new bull bar weighs 65kg. The roof rack adds 30kg. The long-range tank adds 40kg of steel before you even fill it. How much payload have you lost? The simulator includes all your aftermarket gear.
If your vehicle's towing capacity is close to your caravan's ATM, every kilogram matters. The simulator helps you find the best loading arrangement to stay within all limits simultaneously.
A tow simulator is a digital tool that models your complete tow setup — vehicle, caravan, cargo, passengers, and accessories — and shows you how weight is distributed across the combination. Unlike a basic weight calculator that only checks totals, a simulator shows you WHERE weight is sitting and how it affects stability, towball load, and axle weights. It lets you experiment with loading changes before you physically move anything.
A weight calculator checks whether your totals (GVM, ATM, GCM) are within limits — it gives you a pass or fail. The tow simulator goes deeper: it models weight distribution across cargo zones (front, middle, rear of the caravan), shows how your loading affects towball percentage, displays sway risk indicators, and lets you drag items between zones to see the impact in real time. Think of the calculator as a weighbridge check, and the simulator as a full loading analysis.
The most valuable times to use the simulator are: before buying a caravan (will your vehicle handle it?), before a long trip (is your load distribution safe?), after adding new accessories like solar panels or tool boxes (how does the extra weight affect your setup?), and whenever you're carrying significantly more water, fuel, or gear than usual.
The simulator checks and visualises: total vehicle and caravan weights against legal limits (GVM, ATM, GCM), towball download as a percentage of caravan loaded weight (8-14% safe range in Australia), weight distribution across caravan loading zones, sway risk based on your towball percentage and rear overhang loading, and a GCM donut chart showing how close you are to your combined mass limit.
Yes. The simulator connects to your KamperHub garage, so it loads your real vehicle and caravan specs automatically. It also pulls in any aftermarket accessories you've added (bull bars, tool boxes, roof racks, solar panels) and caravan accessories, giving you a realistic simulation based on your actual setup — not generic numbers.
The tow simulator is available on KamperHub's Pro plan ($49/year). The free plan includes a weight compliance dashboard that checks your GVM, ATM, GCM, towing capacity, and towball percentage. The simulator adds visual weight distribution modelling, cargo zone management, sway risk analysis, and the ability to experiment with different loading scenarios.
