Northern Western Australia’s dry season, stretching from May to October, is the perfect time to head off on that long-awaited road trip. Whether you’re towing a caravan to Broome, setting up camp in Exmouth, or chasing sunshine in Coral Bay, the last thing you want is vehicle trouble halfway up the coast.
Before you load up the car and hitch the caravan, our checklist helps ensure your 4WD is ready for the kilometres ahead. From suspension and steering to weight compliance and performance, we’ve covered the essentials.
1. Check the suspension on your towing vehicle
Your suspension takes the brunt of the trip, especially on long, corrugated roads or gravel tracks. Even well-maintained highways up north can get rough, and if your shocks or coils are already worn, the extra weight and heat will push them over the edge.
What to look for:
- A sagging rear end when loaded
- Bouncy ride or “floaty” steering
- Uneven tyre wear
- Loud creaks or knocks over bumps
Before you leave, get a suspension check. If you’re carrying heavier gear than usual or planning off-road detours, consider upgrading to heavy-duty coil springs or airbags. They’ll keep your vehicle level, stable, and far more comfortable for long stretches.
2. GVM and load compliance
It’s easy to underestimate how quickly your gear adds up, tools, fridges, extra water tanks, jerry cans, generators, solar panels, recovery gear… Before you know it, you’re over your legal GVM (Gross Vehicle Mass), which can affect your insurance, handling, and braking performance.
What to check:
- Get your fully loaded setup weighed
- Compare it to your manufacturer’s GVM ratings
- Know your axle load limits, too
If you’re over your weight limit, a certified GVM upgrade increases your legal payload capacity and gives you peace of mind on the road. It’s a smart investment for touring setups, especially if you’re loaded up with camping gear, tools, water, and extras for long-term travel. Staying compliant isn’t just about safety, it protects your insurance and helps your vehicle perform the way it should under load.
3. Inspect your caravan suspension
Caravans endure just as much punishment as the tow vehicle, sometimes even more. Uneven roads, potholes, and long distances put serious strain on every nut and bolt. If your caravan’s suspension isn’t up to scratch, you could be looking at cracked shackles, broken leaves, or worse.
Watch for:
- Worn or “flogged out” bushes
- Loose shackles or U-bolts
- Uneven ride height
- Squeaking or knocking when towing
Caravan suspension failures are common on long trips, especially when the caravan is fully loaded. If you’ve noticed poor handling or the caravan just doesn’t feel right, get it checked, or consider upgrading to a more robust suspension setup.
4. Steering & wheel alignment
Steering that pulls or feels vague might not seem like a big issue around town, but it becomes exhausting, and dangerous, over long distances.
Signs of steering trouble:
- Pulling to one side
- Excessive play or vague steering response
- Vibrations through the wheel
- A car that doesn’t “track straight” on highways
Before you go:
- Book in for a steering and suspension inspection
- Get a wheel alignment, especially after loading your vehicle
- Check for worn tie rods, ball joints, and bushings
Even a minor misalignment can cause rapid and uneven tyre wear, reduce fuel efficiency, and make your vehicle harder to control, especially when towing. Over long distances, that slight pull or vibration adds up, making your trip far more tiring than it needs to be.
5. Monitor your EGTs to keep your engine running cool
Towing a fully loaded caravan or boat? Your engine will be working overtime. A Torqit performance exhaust system helps your vehicle breathe easier, lowers exhaust temperatures (EGTs), and increases torque, especially in the low rev range.
Benefits of upgrading before your trip:
- More towing power
- Smoother throttle response
- Better fuel efficiency
- Lower EGTs (Exhaust Gas Temperatures) for improved engine longevity
- Less stress on the engine on long climbs and in hot weather
If you’re heading into warmer regions with a fully loaded setup, a Torqit performance exhaust can make your drive safer, more efficient, and far more enjoyable. By improving exhaust flow and lowering EGTs, it helps your engine run cooler under pressure, especially when towing uphill or covering long distances in the heat.
6. Check tyres & brakes
These are your two biggest safety factors on the road, and they’re often the most overlooked.
Tyres:
- Check tread depth, pressure, and sidewall condition (don’t forget the spare!)
- Adjust tyre pressures for load and road surface
- Consider all-terrain or light truck tyres if you’re heading off the bitumen
Brakes:
- Inspect pads, rotors, and fluid
- Make sure your caravan brake controller is set correctly
- Test everything under load, not just while the vehicle is empty
Stopping power matters even more when you’re towing heavy loads or travelling long distances. Worn pads, low brake fluid, or uneven tyre wear can seriously affect your ability to brake safely, especially in an emergency.
7. Underbody & fluids check
From corrugated roads to unexpected water crossings, your underbody and fluids face some of the toughest conditions on the trip.
Inspect and top up:
- Engine oil and filter
- Coolant (critical for hot-weather towing)
- Transmission and power steering fluid
- Brake fluid
- Battery condition
Underbody check:
- Look for loose bolts, damaged bash plates, or cracked mounts
- Clean out any caked-on mud or dirt
- Grease suspension points where needed
The parts you don’t see under your vehicle are doing some of the heaviest lifting, especially on rough or remote tracks. Taking the time to inspect and maintain your fluids and underbody can prevent breakdowns, improve performance in extreme conditions, and extend the life of key components. A few small checks now could save you a major repair bill later.
8. Touring toolkit essentials
Even with the best vehicle prep, things can, and do, go wrong when you’re hours from help. A well-stocked touring kit can make all the difference between a quick roadside fix and a major delay. Whether you’re dealing with a flat tyre, electrical fault, or getting bogged in soft sand, having the right gear on hand keeps you safe, self-sufficient, and in control.
Essential Gear to Keep On Board:
- Tyre repair kit & compressor
- Recovery gear (snatch strap, shackles, traction boards)
- First aid kit
- Fire extinguisher
- Spare coolant, oil, and fuel
- UHF radio or satellite phone for remote regions
A bit of preparation goes a long way, especially when you’re off the beaten track or out of phone range. Having the essentials on board means you can keep moving, stay safe, and enjoy the road ahead.
Long drive with little passengers? Try this
If you’re travelling with the kids, few thoughtful extras can make those long stretches much smoother and far more enjoyable:
- Pack snack boxes with easy-to-grab favourites (no-mess fruit, trail mix, crackers)
- Download offline entertainment (movies, podcasts, audiobooks, games)
- Bring a spare USB power bank for charging devices in the backseat
- Keep a travel potty or toilet paper handy for roadside stops
- Create a “surprise bag” with toys or puzzles to hand out every few hours
A little planning goes a long way in keeping the peace (and the boredom at bay) during those long-haul drives.
