Caravan Towing Safety: The Complete Guide for Australians

Towing a caravan safely takes knowledge, preparation, and a few rock-solid habits. Whether you’re new to the lifestyle or already clocking up kilometres, this guide walks you through equipment, pre-trip checks, loading and weights, driving techniques, and emergency prep — with practical Australian context. Use it as your baseline, then branch into the “Read More” articles to go deeper where you need.

1. Essential Equipment for Safe Towing

Your kit is half the battle. Start with the right tow vehicle and a fully compatible, properly fitted hitch and braking setup.

Tow Vehicle Selection

• Match capacities with margin: Your car’s braked tow rating, GVM, GCM, rear axle limit, and maximum tow-ball download must comfortably cover your caravan’s ATM and real-world tow-ball mass (TBM). Leave 10–20% margin — you’ll fill it with people, fuel, water, and gear.
• Cooling & driveline: Heavy towing stresses auto transmissions and engines. Factory tow packages, extra cooling, or lower final-drive ratios can help. Use manual/“sport” mode to control gear selection on hills.

Coupling & Hitch

• Type: Common options are a 50 mm ball coupling (on-road) or an articulating off-road coupling (e.g., DO35/DO45 style) for rough tracks. Both the towbar tongue and the coupling must be rated for your loads.
• Setup: Correct hitch height keeps the caravan level (or very slightly nose down). Fit the right shank/height or adjustable hitch head; torque the mounting bolts to spec and use rated pins/clips.

Safety Chains & D-shackles

• Cross the chains under the drawbar so they can cradle it if the coupling lets go.
• Length matters: Enough slack to turn, not so long they drag. Use rated shackles attached to the vehicle’s designated points.

Brakes, Controller & Breakaway

• Electric trailer brakes: Required above light trailer thresholds — they reduce stopping distances and improve stability.
• Brake controller: Fit a quality unit and set the gain so a firm stop feels smooth (no grab; no push). Use the manual override lever to gently check the van brakes at low speed before every leg.
• Breakaway system: For heavier vans — test battery/state-of-charge and switch. Cable must be dedicated (not through chains) and clipped to the tow vehicle.

Weight Distribution Hitch (WDH) & Sway Control

• WDH: Transfers some drawbar load from your vehicle’s rear axle to the front axle and the van axles. It improves balance but doesn’t increase legal limits.
• Sway control: Friction bars or integrated electronic stability systems (ESC/ATC) can help arrest sway events. They’re a confidence booster for long rigs and crosswind areas.

Visibility & Monitoring

• Towing mirrors: If the van blocks your view, mirrors are legally required. Adjust to see along the sides and the lane immediately behind.
• TPMS (Tyre Pressure Monitoring System): Monitor tyre pressures and temperatures on both tow vehicle and caravan. Early alerts beat roadside heartbreak.
• Anderson plug & wiring: Use robust connectors for charging and ESC. Keep the 7/12-pin plug clean, strain-relieved, and corrosion-free.

2. Pre-Trip Checks & Ongoing Maintenance

Make this your ritual. Five minutes here saves hours on the shoulder later.

Tyres & Wheels

• Pressures (cold): Set for the job: highway vs corrugations vs sand (see “Tyre Pressures 101”). Re-check when temps swing or loads change.
• Age & condition: Replace at ~5–6 years even if tready. Check sidewalls for cracks; inspect the spare.
• Wheel nuts & bearings: Torque wheel nuts before departure; re-torque after the first 50–100 km. Spin hubs at stops — any rumble or one hub hotter than the others? Investigate.

Lights, Electrics & Charging

• All lights go: Indicators, brakes, tail, hazards, number plate.
• Connectors: 7/12-pin and Anderson — snug, clean contacts, cables secured (no dragging).
• Battery/solar: Confirm resting voltage and that charge sources (alternator/DC-DC/solar/240V) work as expected.

Brakes & Suspension

• Controller test: At walking pace, gently apply manual override — you should feel the van tug.
• Running gear: Check shocks for leaks, bushes for play, handbrake for correct travel.

LPG (Gas), Water & Appliances

• Gas: Hoses in date, regulators intact, connections bubble-tested (soapy water) when cold. Store a fire extinguisher (ABE) and fire blanket near the galley.
• Water: Fill tanks, run pump, check for drips at joins. Hot water system cycles normally on gas and/or 240V.
• Fridge: Pre-chill; confirm mode (12V while towing if appropriate, gas/240V when camped, per manufacturer guidance).

Final Walk-Around (Before You Roll)

• Hitch pinned and clipped; WDH latched; safety chains crossed; breakaway clipped to vehicle (not the chain).
• Jockey wheel stowed; stabilisers up; steps in; doors/lockers latched; hatches closed; awning locked.
• Inside: cupboards latched, heavy items low/over axle, nothing loose to become a missile.

3. Loading & Weight Distribution (Keep It Stable)

Balance is everything. A well-loaded van tows calmly; a tail-heavy van invites sway.

Know Your Limits

• Car: GVM (max vehicle mass), rear axle load, tow rating, max tow-ball download, GCM (car + van).
• Van: Tare (as built), ATM (max loaded unhitched), GTM (max on van axles when hitched), and TBM (tow-ball mass).
• Targets: TBM typically ~6–10% of van’s loaded weight, within vehicle and van ratings.

How to Check Weights (Simple Weighbridge Method)

1. Car only: Weigh the tow vehicle without the van to confirm its baseline (and front/rear axle loads if possible).
2. Van axles: With the van hitched, park van axles on the pad (car off) to get axle load (≈ GTM).
3. Combined: Weigh the whole rig to check you’re below GCM.

From those three, you can infer loaded TBM and confirm none of the limits are exceeded.

Pack Like a Pro

• Heavy items: Low and close to the van’s axle line. Avoid loading the rear bumper.
• Left–right balance: Keep it even; uneven loads = weird handling and tyre wear.
• Secure the lot: Use tie-downs and non-slip liners. Shifting loads change TBM mid-trip.

4. Driving Tips for Safer, Smoother Towing

Confidence is smooth inputs and sensible margins. These techniques keep your rig calm and predictable.

• Speed & spacing: Sit around 90–100 km/h and hold a 5–6 second gap. More in wind or traffic.
• Braking: Brake earlier and more gently. Use the manual trailer brake override to settle minor sway (lightly), but ease off the throttle simultaneously.
• Hills: Downshift early on climbs; use engine braking on descents to avoid hot brakes.
• Turns: Take wider lines; your van cuts in tighter than the car. Mind kerbs, bollards and fuel station islands.
• Overtaking: Only with a long clear run. Build speed gradually, leave a big buffer before returning to lane — especially past road trains.
• Wind & trucks: Expect a push–pull effect as trucks pass. Hold a steady wheel, ease off slightly, let the rig settle — no sharp corrections.
• Reversing: Go slow; make small steering inputs; use a spotter with agreed hand signals. A rear camera helps, but don’t rely on it alone.
• Fatigue: Stop every 2 hours. Swap drivers if possible. Hydrate and snack — towing is mentally heavier than solo driving.
