Caravan Security for Remote Travel: The 4-Layer System That Keeps Our Rig Safe Off-Grid

Caravan security is a growing issue in Australia. Highway pull-offs, free camps within 30 km of major arterials and even fuel stations are now where opportunists work. The thieves are not always amateurs. They turn up in their own vehicle with bolt cutters, a generic coupling-lock pick, and a spare 50 mm tow ball. If your rig is parked and nothing makes it harder than the van one bay over, yours is the one that goes.

Security on a long trip is not about turning the van into a fortress. It is about adding layers, none of which add weight you cannot afford, draw power you cannot spare, or take up storage you do not have. Below is the four-layer system we use on our hybrid. It has held up across the Gibb, Cape York, the Savannah Way and 2 years of mostly free and low-cost camping.

The Situational Layer: The Place and Limiting Risk

The cheapest, lightest, most effective security layer you have is where you choose to stop and how you set up. Hardware is the last line, not the first.

Camp Selection and the Vibe Check

Risk profile changes by camp type:

• Caravan parks (powered): Lowest theft risk for the rig itself. Higher risk for unsecured external gear (bikes, generators, solar blankets) left unsecured overnight.
• National park campgrounds: Generally very low risk. Camp hosts, ranger patrols and a stable community of self-funded travellers mean opportunists stand out. Wildlife is a bigger threat to your food than people are to your rig.
• Council and showground camps: Mixed. A camp inside a town boundary with passing local traffic is different to one tucked behind a sports ground three streets back.
• Roadside free camps near highways: Highest risk profile. The closer you are to a major corridor (Stuart, Bruce, Eyre, Great Northern) and the more anonymous the bays look, the higher the chance of a 2 am drive-through by someone scouting.
• Station stays: Generally low risk. Private property, gate kept and a working community on site. Stations along the Gibb like Home Valley and Mt Elizabeth are some of the most secure overnight stops in the Kimberley.

The golden rule is simple: if a camp feels wrong, leave. In tens of thousands of kilometres on the road, we have never had a single item stolen. One reason for that clean record is knowing when to drive away. We actively check recent reviews on community apps and routinely cross potential camps off our list before we even arrive if there are reported security or antisocial issues. When we do pull up, we let the environment dictate the stay. Lone cars circling at dusk, fresh broken glass across a turnout, or groups that fall silent and stare when you arrive: these are not paranoia; they are data. Listening to your gut and finding another spot might cost you 40 minutes of daylight, but ignoring a red flag can cost you your gear or your safety.

Rig Positioning as a Deterrent

How you park makes a hook-and-run theft physically impossible without effort, which is usually enough. The opportunist wants 60 seconds, not 6 minutes.

• Block the A-frame with the tow vehicle. Park the 4WD across the front of the coupling when you unhitch, not beside the van. The thief now has to move two vehicles instead of one.
• Awning out, chocks down, levellers in place. A fully deployed camp signals you are present and committed. A van that looks like it could be hooked and gone in two minutes is the target.

The Walkaway Routine

Most theft from caravans is opportunistic and happens during 10-minute stops, not overnight. Fuel stations, lookouts, supermarket car parks. The walkaway routine is a 30-second habit:

• All blinds and curtains drawn before you step out. If a prowler cannot see a Garmin on the bench or a camera bag on the dinette, the rig is not worth breaking into.
• Tow vehicle locked even for a 90-second duck into a servo. Keys on you, not in the cupholder.
• External door deadlocked, not just on the latch. The triple-lock handle is only useful if you actually engage the deadbolt.
• Generator, jerry cans and any portable gear on the A-frame are either chained or stored out of sight. A petrol jerry sitting unsecured at a Coles car park in Mt Isa is gone the moment your back is turned.
• Solar blankets folded and packed inside the vehicle, not left out drying. A 200 W folding blanket costs $600 to $900 and takes 20 seconds to slide into a backpack.

The Camp Community

The buddy system is the most underused security tool on the road. A short conversation when you pull in (where are you headed, how long are you here, where have you come from) does two things. It establishes you as a person rather than a target and gives you a neighbour who notices when something is off.

We had neighbours flag a stranger walking around our rig at Cape Range while we were snorkelling, and we did the same for a couple at Eighty Mile Beach when something didn’t seem right. Five minutes of yarning when you arrive buys you eyes on your rig every time you walk away. It is free, it weighs nothing, and it works better than any alarm.

The Human Layer: Personal Security and Internal Assets

This layer is about what happens if someone actually tries to get inside or moves on you while you are in the van.

Reinforcing Vulnerable Entry Points

Most modern caravans ship with reasonable hardware that owners then never test. Walk around your rig and apply real force to:

• Window latches. Plastic awning windows on older vans can be popped with a flat-bladed screwdriver in seconds. Upgrade to security latches or fit aftermarket internal locking bars on the windows nearest the bed and lounge.
• The main door. The triple-lock security door is a strong piece of hardware, but only when the deadbolt is engaged. Pull on the door hard with just the handle latch on. On many vans there is enough play that a credit card or flat tool can be worked into the gap. Engage the deadbolt every time you close the door, including from the inside at night.
• Pop-top canvas zips. Pop-top vans are the easiest break-in in the carpark. A simple zip pull from outside opens the canvas. Fit a small carabiner or padlock through the internal zip pulls when you are away or asleep.
• External hatches and bin doors. The boot, gas locker and battery box locks are usually cam locks with universal keys. If your locks all key alike with the previous owner’s set, replace them. The keys are sold in two-packs at any caravan accessory store.

Exterior 12V Motion Lighting

Dark spots around a van are an invitation. The cheapest, lowest-draw way to remove them is to install a pair of 12V PIR motion lights at the front and rear corners of the rig, wired to a switch on the 12V panel so you can isolate them when not in camp.

Specs to look for:

• LED, 5 W or less per fixture (most are 3 W to 4 W).
• PIR sensor adjustable to 3 – 8 m detection range.
• Hold time configurable to 30 – 60 seconds.
• IP65 rated minimum for dust and water resistance.

Total draw when triggered is 0.5 – 0.7 A per fixture at 12V. The standby draw is in the milli-amperage range. Over a typical evening, you will use under 2 Ah even if the lights cycle several times. That is well within the budget of any van running 200 Ah or more of lithium with solar. If you are tight on capacity, check our caravan solar panel efficiency guide for ways to recover that headroom.

A solid alternative (or supplement) is a set of standalone solar PIR motion lights. These have come a long way in the last few years. A decent unit has its own 4 – 6 W solar panel on top, an internal lithium battery, an integrated PIR and an LED head, all in one IP65 housing for $30 to $60 each from any hardware store. There is no wiring back to the van, no draw on your house battery and no auto-electrician involved. Stick them to the side of the van with 3M VHB tape or a magnetic mount, or clamp them to the awning rail and the annexe pole. The advantage for off-grid is that they charge themselves from the same sun your panels are using and they keep working even when the van is unhitched or parked in storage at home. The trade-off is that the lithium cells in cheaper units fail after 2 to 3 years of full sun and 40 °C summers, so budget for replacing them periodically. For travellers who do not want to cut into wiring looms or who park the rig at home for months between trips, solar units do the job with less fuss than a hardwired install.

The point is not to spotlight your camp. It is to make a prowler feel exposed the moment they step into the dark area around the van. They almost always walk away.

The Internal Safe

Anything important that you cannot replace with insurance or a phone call belongs in a bolted safe. That list is shorter than people think:

• Passports, driver’s licence backups, Medicare cards.
• Emergency cash ($500 to $1,000 in mixed denominations for fuel and tyres in places where EFTPOS has dropped out).
• Spare keys to the tow vehicle and caravan.
• High-value camera bodies and lenses when not in use.
• Backup external hard drive with photos and trip data (ideally you want two sets of backups).

A small heavy-gauge steel safe (typical dimensions around 250 x 200 x 200 mm) can weigh as little as 1 kg empty and bolts directly to the chassis or a structural cross-member. Do not screw it into the plywood floor only. The whole point is that a thief with 90 seconds cannot rip it out. Bolt through to steel.

Best location is under a bed base or inside a permanent under-bench cabinet where it is hidden from view and the bolt heads are protected from the inside. Take a photo of the bolts after installation. If the safe ever appears moved, you will know immediately.

An example of caravan safes is Caravan Safe.

Fire Safety: The Compliance Shift

Smoke alarm regulations for caravans have tightened. The short version for travellers as at 2026:

• Queensland has been the leader. From 1 July 2024, all newly registered or transferred Queensland caravans and motorhomes must have a compliant photoelectric smoke alarm. By 1 January 2027, every Queensland-registered caravan and motorhome must comply.
• NSW and Victoria: Both states require a compliant photoelectric smoke alarm inside registered caravans and motorhomes. Note: NSW law requires that the unit have a physical “hush” button to silence false alarms while cooking.
• WA, SA, NT, TAS, & ACT: Do not currently have vehicle registration mandates for smoke alarms, but local fire authorities strongly recommend them.
• The Unit Standards: Alarms must comply with AS 3786-2014, use photoelectric technology (older ionisation sensors are ineffective for smouldering caravan fires), and be powered by a 10-year non-removable sealed lithium battery.
• Placement: You need at least one ceiling-mounted alarm in the main sleeping area. If anyone sleeps out in the annexe, you are legally required to put a secondary alarm out there as well. In this scenario, choosing a wirelessly interconnected pair (in which one triggers the other) is the safest move.

A 10-year sealed lithium photoelectric alarm is the only practical choice. There is zero ongoing battery maintenance, just an annual button test and a quick vacuum to keep dust out of the sensor. They only cost between $25 and $60. If you’ve just bought a used van, check the manufacture date stamped on the back of the unit; by law and standard, you must replace the entire unit every 10 years.

The Hardware Layer: Caravan Security

The Cruisemaster DO35 Hitch Lock (or equivalent for other hitch designs)

If you tow with a DO35 (or DO45 V1) coupling, the Cruisemaster security pin or something similar is the single highest-value piece of security hardware you can carry. We use a Kovix lock, and it is the only one we leave on full-time when parked.

How it works: the assembly comes with a steel dummy pin, a lock chamber with a dust cover and two keys. The dummy pin inserts into the DO35 universal joint from the bottom, protruding through the top. The lock chamber then fits over the protruding tip and locks with the key. The coupling is now physically inoperable. No tow ball can connect to it. The articulating head cannot accept any standard hitch.

Why it suits remote travel:

• Weight: The full assembly is around 500 g. A serious steel wheel clamp is 8 – 15 kg.
• Footprint: The assembly is small and, when not in use, easily stows away in a cupboard.
• Durability: Stainless steel construction. We have run ours through Gibb River dust, Cape York mud and Bay of Fires salt spray with no failure. A light spray of silicone or WD-40 on the mechanism every few months keeps it sweet.
• Speed: 10 seconds to fit, 10 seconds to remove. Fast enough that you actually use it every time you unhitch, which is the whole point.

The DO35 lock is suitable for DO35 V2, V3, V3 Plus and DO45 V1 couplings. If you have an older DO35 V1, you need to check compatibility with the supplier. If you have a different brand coupling (Treg, Mchitch, AT35) there are equivalent dedicated security pins from each manufacturer. Buy the one made for your specific coupling. Generic universal hitch locks are easier to defeat, as is the bush trick of using an adjustable spanner and a padlock.

You may have seen people thread an adjustable spanner through the hitch, then a padlock through the hole at the end. This is very easily defeated. We don’t recommend this.

The “No Wheel Lock” Reality

The heavy steel wheel clamp is the most visible security product on the market, and the one most long-term travellers eventually leave at home. The reasons are practical, not paranoid:

• Weight: A serious clamp rated for 16-inch off-road tyres is 8 – 15 kg. Carrying one on a 1,500 kg ATM van is 1% of your useful payload sitting in a tub for the entire trip.
• Storage: Wheel clamps are awkward shapes. They live in the front boot or a tunnel boot, taking up space that should be used to hold spare water, recovery gear, wood or, more importantly, beer.
• Dust and mud: The locking mechanisms on most steel clamps jam after 1,000 km of corrugation dust. We have heard of travellers on the Gibb who fitted theirs at the start of the trip and could not remove them three weeks later without a hammer.
• Practical use: If you are moving every 1 – 3 nights, you will stop fitting the wheel clamp by day 5. A security device you do not use is not a security device.

The trade is straightforward. You drop the high-visibility wheel deterrent and you lean harder on the hitch lock plus rig positioning. To compensate:

• Always fit the DO35 lock the moment you unhitch. Not later. Now.
• Add the GPS tracker as the recovery layer if the worst happens (covered in a later section).
• If you are leaving the van in long-term storage between trips (3+ weeks at home or in a paid yard), a wheel clamp makes sense. Carry it at home, not on the road.

Securing External Assets

The A-frame toolbox, gas cylinders and jerry cans are prime targets for opportunistic theft. A 9 kg LPG bottle is worth $150+ if you have to replace it in a remote area, and it takes 20 seconds to lift from its mount. A 20 L jerry of diesel is worth $60+ and goes the same way. Not to mention the inconvenience it may cause.

Hardware that works:

• A-frame toolbox: Most ship with a generic cam lock that opens with the same key as 80% of other vans on the road. Either replace the cam lock with a keyed-different unit or fit a hasp and a CISA, Abus or similar shrouded padlock.
• Gas bottles: A 6 mm or 8 mm hardened chain (galvanised, 1.5 – 2 m length) wrapped through the bottle handles and around the A-frame, secured with a single shrouded padlock, stops the lift-and-walk theft. Do not use cheap brass-bodied padlocks. They cut in seconds with bolt cutters.
• Jerry cans: Use the same chain-and-padlock setup through the carry handles, anchored to the jerry can holder or A-frame. Better yet, do not leave full jerries unattended. Decant the fuel into the main tank as soon as there is the capacity.
• Spare wheel: If your spare is rear-mounted on a swing-out carrier, fit a locking wheel nut or use the existing carrier lock. If it is under the rear, a short chain through the rim and around the chassis is enough to make it not worth the effort.

Number Plate Theft

Cloned number plates from stolen caravans are used to mask other stolen vehicles, run tolls and dodge speed cameras. The plate itself takes 30 seconds to replace with a Phillips head, and it’s replaced for free at the rego centre. The downstream problem is your plate sitting on someone else’s stolen ute three states over.

The fix is a $10 packet of one-way security screws. They drive in with a standard Phillips bit but cannot be unscrewed because the head is shaped to slip past the screwdriver in reverse. Fit them to both the caravan plate and the tow vehicle plate. Five minutes of work, problem closed.

The Electronic Layer of Caravan Security: Alarm and GPS

12V Caravan Alarm Systems: What to Look For

A good off-grid caravan alarm has four jobs: detect, deter, alert and where possible, immobilise. The system has to do all of that on standby power that does not flatten your house battery overnight.

Specifications to check before you buy:

• Standby current draw: Under 30 mA is good. Under 15 mA is excellent. At 20 mA standby, a system draws around 0.5 Ah per day, which any van with solar will replace by mid-morning.
• Sensor types: Magnetic reed switches on the entry door (and pop-top hatch if applicable), an internal PIR motion sensor and a movement detector (gyroscope or tilt sensor) on the main unit.
• Siren output: 100 dB or louder. At 105 dB you will hear it across a campground.
• Pairing capacity: The ability to add additional door switches and motion sensors for larger rigs or bunk vans.
• Remote operation: Two key fobs minimum so the system arms and disarms cleanly without you having to open the door first.

The system we use is the WiTi Anti-Theft. It is designed and manufactured in Australia at their factory in Joondalup, Western Australia, with national distribution managed from Melbourne. It is the only dedicated caravan alarm system we are aware of that directly integrates with the trailer’s electric brake circuit. If its internal gyroscope detects a hook-up theft or towing attempt, the system instantly flashes the external lights, sounds a 105 dB siren, and locks the electric brakes down hard. The van instantly becomes a 1.5 to 3-tonne static object that physically cannot be dragged away.

The base WiTi kit includes the main unit, two remote controls, a wireless PIR motion sensor, a wireless magnetic door switch, an external status LED, the siren horn and a wiring loom. It pairs additional sensors (up to 20 devices) if you want bunk room PIRs or pop-top switches. The gyroscope is programmed to ignore side-to-side rocking from wind, which kills the false-alarm problem that plagues cheaper systems.

Wiring is straightforward for a competent owner with 12V experience, but if you are not comfortable with auto-electrical work, get an auto sparky to fit it. The whole install is half a day on most rigs.

The other reason we run WiTi is that the base alarm is the platform for two optional add-ons that earn their keep on a long trip. The first is the WiTi Wireless Brake Controller, which pairs with the alarm unit and replaces a traditional in-cab brake controller. It is a portable plug-and-play unit powered from a 12V or USB-C socket in the tow vehicle, with no permanent wiring. The key feature is Hill Descent Assist: a conventional proportional controller relies on inertia (deceleration) to apply the van brakes, so when you feather the brakes down a long descent to hold speed, almost no braking gets sent back to the van. The trailer ends up pushing the tow vehicle down the hill. This can cause caravan sway. The WiTi controller uses an internal gyroscope to measure the angle of descent and applies van braking proportional to the slope, regardless of inertia.

The second add-on is the WiTi SafeTrack GPS module, which plugs directly into the core anti-theft unit. It operates via the WiTi SafeTrack app and has two tracking subscription tiers to fit how you travel: the low-cost QProtect tier ($7.50 per month or $49 billed annually) for on-demand locating, or the premium WiTi Track plan ($24.50 per month or $228 billed annually) for full 24/7 live monitoring and instant movement alerts. The newer SafeTrack hardware includes Wi-Fi connectivity, allowing it to connect to your onboard Starlink network and continue transmitting tracking data when you are out of cellular range.

The advantage of the WiTi GPS is that it is hardwired directly into the van’s 12V system, so there is no internal battery to pull out and recharge every few months. The downside is that a smart thief who targets the house battery bank or cuts the main wiring harness can instantly disable it.

This exact vulnerability is why we still run a SolidGPS unit as a completely hidden, battery-powered backup tracker. This two-tracker, “belt-and-braces” approach gives us peace of mind: one system tied to the van’s electrical system for everyday live tracking and remote-control convenience, and a second, completely independent unit hidden deep inside the frame that keeps operating even if the entire electrical system gets vandalised.

Beyond towing control, choosing the WiTi brake controller adds two utility upgrades: integrated caravan levelling and real-time Tyre Pressure Monitoring (TPMS). The built-in electronic levelling function uses the system’s gyroscopes to display exact pitch and roll angles on your phone or controller screen. This takes the guesswork and yelling out of setting up ramps at uneven campsites. Paired with the wireless TPMS sensors, you also get live, in-cab pressure and temperature alerts straight from your caravan and tow vehicle tyres, giving you an early warning on slow leaks, blowouts or dragging bearings before they cause catastrophic damage on remote tracks. In our opinion, a TPMS on a caravan is a necessity.

GPS Trackers: Smart Placement and Management

A GPS tracker is not a prevention. It is recovery. If your van is gone, the tracker is what tells the police where to look. Treat it accordingly.

The unit we use is the SolidGPS tracker. It is Australian-designed and assembled, runs on 4G with a multi-network SIM built in, and the rechargeable battery model lasts 3, 6 or 12 months between charges, depending on the variant you buy. It updates location every 2 minutes when the tracker detects movement and once every 24 hours when stationary. Geofence alerts (Watchdog mode) send an instant notification to your phone if the van moves outside the perimeter you set.

The current Solid GPS subscription is $69.99 per year (August 2026), which covers the SIM data, app access, alerts and history. No telco contract, no setup. A new unit comes with a free one month subscription (look below for details on how to get an extra month).

Placement is everything. The two rules:

• Do not hide it where a thief would look. Inside the front boot, under the bed mattress, in the glovebox-equivalent are all the first places a thief checks. Assume they know GPS trackers exist.
• Hide it where you can still reach it for recharging. A tracker that needs you to dismantle the chassis to top up the battery is one you will stop charging by month two.

Practical hiding spots we have used:

• Inside a wall cavity behind a 12V panel face plate (4 screws to access).
• Inside an overhead cupboard behind a removable cover.
• Cable-tied inside the chassis rail behind a sound-deadening mat.
• Inside the upholstery void under a couch base.

The signal passes through fibreglass, aluminium and most plastics. It will struggle through dense steel boxes (do not put it inside a metal toolbox or safe). Test the location with the app before you commit. Walk 100 m away from the van and check that it is still reporting accurately.

Two more things to manage:

• Battery alerts: The app notifies you when the tracker hits 30%. Recharge then, not later. A flat tracker is no tracker.
• Geofence size: The perimeter is set at 50 m around camp.

If the budget allows, run two trackers. One in an obvious-ish spot that a thief might find and disable (the decoy), and one well hidden. A great option would be a smart tag. Most professional vehicle thieves know to do a tracker sweep. The decoy buys you time. The WiTi GPS only transmits once every 24 hours if there is no movement, so it is not easy to detect before movement.

Securing Portable Gear

External assets get stolen far more often than whole vans. The gear most worth locking down:

• Generators: A 2 kW inverter generator is $1,000 to $2,500 and walks away in 15 seconds. Chain it to the A-frame or the tow vehicle towbar with a hardened chain and shrouded padlock whenever it is running unattended or stowed outside overnight.
• Solar blankets: Avoid leaving them out when you walk away from camp in suspect areas. They roll up small enough to disappear into a backpack. Consider placing them inside the van or locked in the tow vehicle when you are not present. That said, we have always left ours out and never had it go missing, but it now looks well used and tired.
• External fridges: If you run a slide-out fridge on a drop-down kitchen, fit a hasp and padlock to the slide. The fridge is $800 to $1,500 of replaceable freight.
• Bikes: A pair of decent e-bikes is $4,000 to $8,000. Use a U-lock through the frame and the bike rack, not a cable lock. Cable locks cut in 4 seconds with $30 bolt cutters from Bunnings.
• Recovery gear: Maxtrax, snatch straps and a quality bow shackle set on the roof rack or rear bar are an easy lift. Lock them or stow them inside.
• Camp chairs: Not a big financial loss, but losing them is a frustrating inconvenience.

The principle across it all: time is the deterrent. Anything that turns a 30-second theft into a 3-minute theft pushes the opportunist to an easier target.

Putting It All Together

Layered security works because no thief can defeat every layer. Camp selection and rig positioning kill the casual opportunist. The DO35 lock kills the hook-and-run. Motion lights and the alarm kill the closer approach. The safe protects what matters most. The GPS tracker recovers what got through everything else.

None of this is expensive in the context of a $50,000 to $150,000 rig. The full hardware stack (DO35 lock, WiTi alarm, SolidGPS tracker, motion lights, internal safe, plate screws, chain and padlocks) is somewhere between $1,500 and $2,200 fitted. Spread across the life of a long trip, it works out to a few dollars a day.

The pieces that cost nothing are the most important. Trust your gut on a camp. Lock the deadbolt even when you walk 20 m to the toilet block. Have a yarn with the neighbours when you pull in. These habits keep more rigs safe than all the hardware combined.

If you are heading remote, the layers matter most where help is furthest away. For trip-specific prep, see our Gibb River Road for caravans hub and the Kimberley off-grid planning guide, both of which assume your rig is set up to be left at camp while you walk into a gorge for the day. For the weight side of the equation (every kilo of security hardware comes off your payload), our caravan towing weights guide walks through how to budget it properly.
