How you load your caravan matters more than how much you load it. Poor weight distribution is the leading cause of caravan sway — and it's entirely preventable. This guide shows you exactly where to put your gear for safe, stable towing.

Caravan weight distribution refers to how weight is spread across your caravan and tow vehicle. Correct distribution keeps the centre of gravity low and balanced, improving stability and braking. Poor weight distribution can cause sway, reduced steering control, and increased stopping distances even when total weight limits are not exceeded.
When weight is concentrated forward of the axle, the caravan tracks straight and resists sideways forces from wind and passing trucks. Weight behind the axle creates a pendulum effect — the further back, the worse the sway.
Where you place cargo directly affects how much weight presses down on the towball. Too little towball weight causes sway. Too much overloads your vehicle's rear axle and lifts the front wheels, reducing steering grip.
Uneven loading causes uneven tyre wear. One overloaded tyre runs hotter, wears faster, and is more likely to blow out — especially on long outback drives at highway speed. Balanced loading extends tyre life and reduces blowout risk.
Individual axle weights can exceed legal limits even when total weight is fine. Roadside inspections in some states check axle weights — not just totals. Proper distribution keeps you legal at every measurement point.
Think of your caravan as three zones: front, middle (over the axle), and rear. Each zone has a role in keeping your setup balanced and safe.
Side view: weight forward of the axle increases towball download (stability). Weight behind the axle increases sway risk.
The front zone (everything ahead of the axle) contributes positively to towball download. Loading here pulls weight forward, keeping the caravan stable and the towball percentage in the safe range. This should be your primary loading area for medium-weight items.
What goes here: Clothes, bedding, kitchen equipment, pantry items, general camping gear
The area directly above the axle is where your heaviest items should go. Weight here has minimal effect on towball percentage (it's supported directly by the axle) but keeping it low lowers the centre of gravity. This is the safest spot for dense, heavy items.
What goes here: Water tanks, batteries, tools, heavy equipment, tinned food, generator
Everything behind the axle reduces towball download and increases sway risk. The further back the weight, the greater the leverage effect — a 10 kg item at the very rear of a caravan has more impact on stability than a 20 kg item near the axle. Keep this zone as light as possible.
What goes here: Lightweight items only: pillows, toilet paper, empty containers, soft bags
Check your caravan's tare weight, ATM, and ball weight on the compliance plate. Check your vehicle's GVM, GCM, and towing capacity in the owner's manual. These are the boundaries you must work within. If you don't know your numbers, you can't manage them.
Start with the heaviest items — water tanks, batteries, toolboxes, generators. Place them as low as possible, centred over or just forward of the axle. This keeps the centre of gravity low and maintains a safe towball download.
Next, load clothes, bedding, kitchen equipment, and pantry items into the front half of the caravan. This contributes to towball download and keeps weight forward for stability.
Only lightweight items should go behind the axle. Pillows, toilet paper, empty containers, soft bags. If you must put something heavier in the rear (like a bike rack), check the towball percentage afterwards — it may have dropped below the safe 8% threshold.
Walk around the caravan and check it's not leaning to one side. Distribute weight evenly from left to right. An unbalanced caravan wears tyres unevenly and handles poorly in crosswinds.
Your towball download should be 8–14% of your caravan's total loaded weight. Use KamperHub's weight calculator or a towball scale to verify. If it's too low, move weight forward. If it's too high, shift some weight rearward — but keep it close to the axle, not in the far rear.
Before your first trip with a new load configuration, visit a public weighbridge or use KamperHub's weight compliance calculator to confirm all limits are within range. Save your configuration so you can replicate it for future trips.
Fix: The rear boot is convenient but it's the worst place for heavy items. It's behind the axle with maximum leverage. Move heavy tools and equipment to the floor near the axle.
Fix: Water weighs 1 kg per litre. A full 200L tank adds 200 kg — often more than you need. For trips with regular water access, carry 50–75% and top up along the way.
Fix: Bull bars (40–65 kg), roof racks (25–40 kg), long-range tanks (30–50 kg empty), bike racks (15–25 kg). These eat into your payload before you pack a single item. Track them.
Fix: A fridge on one side with nothing heavy opposite creates a lean. Balance heavy items across both sides of the caravan for even tyre loading.
Fix: Adding a new solar panel, air conditioner, or annexe changes your weight profile. Re-check your compliance after any modification — not just when packing for a trip.
Yes. A caravan can be well under its ATM and still experience dangerous sway if weight is loaded too far behind the axle. Sway is caused by insufficient towball download, not just excess total weight. Even a lightly loaded caravan with gear stacked in the rear can become unstable at highway speeds. This is why weight distribution matters as much as total weight — and why checking towball percentage is essential even when you're under all published limits.
Your caravan's axle setup affects how weight is distributed across the wheels and how much flexibility you have with loading.
Most caravans under 2,000 kg ATM have a single axle. All the caravan's weight (minus towball download) rests on two tyres. This makes weight distribution especially critical — there's less margin for error. A heavy rear load on a single axle caravan creates significant sway risk.
Larger caravans typically have tandem (dual) axles, spreading weight across four tyres. This provides more stability and a larger safe loading area. However, weight distribution still matters — rear-heavy loading on a tandem axle caravan can still produce dangerous sway at highway speeds.
Load-sharing (independent) suspension allows each wheel to respond to bumps independently, distributing weight more evenly across all tyres. This is better for off-road travel and provides a smoother ride.
Non-load-sharing (beam axle) suspension connects the wheels rigidly. A bump on one side affects the other side. Weight distribution is more critical with beam axle setups because imbalances have a more direct impact on handling.
Weight distribution directly affects legal towing limits because it changes axle loads and towball weight. Placing heavy items too far forward or rearward can push your vehicle over its GVM or rear axle limit. This means a setup can become illegal even when the caravan's total weight appears acceptable.
Loading the front of your caravan increases towball download — which adds to your tow vehicle's weight. This can push your vehicle over its GVM even when the caravan is under its ATM. The weight calculator checks both simultaneously.
Weight behind the axle reduces towball percentage. Drop below 8% and you enter dangerous sway territory — the leading cause of caravan accidents. The tow simulator shows your sway risk in real time as you move cargo between zones.
Exceeding any weight limit — GVM, ATM, or GCM — can result in on-the-spot fines up to $5,000+ and voided insurance cover. See the state-by-state fines to understand the penalties.
Heavy items should be placed as low as possible and centred over or just forward of the axle. This keeps the centre of gravity low, maintains safe towball download, and minimises sway risk. Never place heavy items in the rear overhang area behind the axle.
Caravan sway is primarily caused by insufficient towball download — usually because too much weight is loaded behind the axle. Other contributing factors include excessive speed, crosswinds, passing trucks, and uneven side-to-side loading. Maintaining 8–14% towball download is the most effective prevention.
In Australia, your towball download should be between 8% and 14% of your caravan's total loaded weight. For example, if your caravan weighs 2,000 kg loaded, the towball download should be between 160 kg and 280 kg. Below 8% significantly increases sway risk.
Load-sharing (independent) suspension distributes weight more evenly across multiple axles, allowing each wheel to respond to bumps independently. Non-load-sharing (beam axle) suspension connects the wheels rigidly, so a bump on one side affects the other. Load-sharing is generally better for weight distribution and ride quality, especially on unsealed roads.
