Security on an off-road caravan is decided at two moments, and neither of them is the moment a unit goes missing. The first is the order: which locks are fitted, how they are keyed, and where the removable items live. The second is the stretch between unloading and sale, when a container of caravans is standing still, in a yard, on somebody else's schedule.
Everything bought after that — hitch locks, wheel clamps, alarms, trackers — either matches a decision made at build time or works around one that was never made. That is why the security conversation belongs with the specification, not with the accessories.
The published specifications are a useful starting point. The 21ft family model lists a coupling lock among its safety features. The 16ft hard-top models list four heavy-duty lockable and adjustable drop-down stabiliser legs — legs that lock in position, which adds a step for anyone trying to move a parked unit.
What the same pages do not state is the entry door lock type, which cargo hatches are lockable, and how many keys ship with a caravan. Treat those as confirmation items rather than gaps. Ask for the lock type, the key count, and whether replacement lock sets can be supplied as spares, because a caravan whose locks cannot be matched in your market is a caravan whose keys have to come from the factory every time one goes missing.
The holder arrangement deserves the same attention. The 16ft and 21ft models both document holders for 2 × 9kg gas cylinders and 2 × 20L jerry cans. On the 16ft models the weight note states that gas bottles and jerry cans are excluded from the published figures, which is a useful reminder that both are separate purchases that sit in holders rather than items built into the shell. Anything carried outside the locked body is easier to remove than anything inside it, so confirm from the drawings where the holders sit and decide whether that position should be lockable or caged for your market.
Seven lines cover most of what an importer can actually control at the factory:
Item five is worth pausing on. A permanently live device is a permanent DC load, so it belongs in the same calculation as the battery bank and the solar array rather than being added in the yard after arrival. The 16ft models document 2 × 100Ah AGM batteries with 300W of solar; the 21ft model documents 2 × 200Ah lithium with 875W. An importer who wants tracking on every unit should size that load at the order stage, and one who does not should still ask where the wiring point is, so the decision stays open.
Losing a key is an inconvenience. Losing track of which key belongs to which caravan, in a yard holding a container load of them, is a stock-control problem — and it is the part of security that no factory specification can solve for you.
The practical version looks like a key register. Every unit enters the register at unloading with its chassis number, the number of keys received, and the name of the person holding them. Spare key sets stay out of the vehicles and out of the sales desk drawer. On a rental fleet, the register is what lets an operator tell the difference between a key that was not returned and a key that was never issued, and it is the document that answers the first question an insurer asks.
Two details make the register easier to keep. First, keyed-alike batches remove the matching problem entirely, so ask about them before the order, not after. Second, a written note of the key and lock supplier, with part numbers, means a replacement can be ordered like any other spare instead of being traced backwards through a build sheet.
Transport is hard on catches and hinges, and a lock that will not turn is usually an alignment problem rather than a security one. Before a unit is parked in its final position:
Transit cover follows the cargo while it is in transit. Once a caravan is unloaded and standing on your ground or your dealer's ground, that risk belongs to somebody else's policy — usually a stock or premises arrangement, agreed separately, and often written before anyone thought about a container of caravans arriving.
Two questions are worth putting to a broker before the first shipment lands. What does stock cover require in the way of records if a unit is taken — identification details, photographs, key records, a movement log? And does the policy treat units stored outside differently from units stored in a locked building? The paperwork those answers imply is a spreadsheet and a camera. Assembling the same records months after a theft, from memory, is a much longer conversation.
A caravan out on hire is protected by the operator's arrangements, but two habits carry across to the dealer side. The first is a handover that records the keys issued, the accessories present and the condition of the unit, because theft and damage are handled as separate events and the paperwork should separate them too. The second is honesty about what a tracking device does: it helps recover a unit, it does not prevent a theft, and it does not replace a lock, a register or a lit yard. Operators who sell security as a promise to their own customers usually end up withdrawing it.
Lock and hitch standards are local, and so is theft pressure. A hitch lock that is common in one market may not fit the coupling you ordered, and a wheel clamp bought sight-unseen may be the wrong diameter for the wheels on the caravan. Ask the dealers in your network what they already sell to end customers, and ask the factory what coupling and wheel specification the units carry, so the two lists meet. Wheel and tyre specification is listed model by model across the off-road caravans for dealers range, which is the quickest way to check what your market's clamp and lock sizes have to suit.
LZM is an off-road caravan manufacturer and exporter in China, supplying dealers, importers and rental operators in Australia, New Zealand and the United States, with more than 3,000 off-road caravans built each year. Security hardware is a small set of lines on a long specification sheet, and it is one of the few where a written question before the deposit is worth more than a purchase after arrival. Specifications vary by model and final configuration, so confirm lock type, key counts, holder positions and spares against the build sheet for your own order.
It is a specification item rather than a standard fitting, so raise it with the order and ask for three things in return: the wiring point the device will use, the parts list for the hardware, and who handles a warranty claim on a device fitted in China but serviced in your market. A tracker connected to the caravan's own DC system also becomes part of its electrical load, which is why it should be settled while the battery and solar specification is still open.
Ask for it in writing on the order. Keyed-alike batches are the single biggest time saver for a rental fleet or a dealer group, and they remove the risk of a customer driving away with a unit that has been opened by the wrong key. If the answer is no, plan for local re-keying and price it before you quote the fleet, not after.
The models document holders for 2 × 9kg cylinders and 2 × 20L cans, and the weight notes exclude both items, so treat them as a separate purchase sourced against your market's cylinder standard. That also means the holder position, and whether it can be locked, is a decision you make rather than one you inherit.
No single item covers a caravan. A lock protects a compartment, a coupling lock protects the hitch, a clamp protects a wheel, and a register protects the stock as a whole. The layer that is usually missing on a first shipment is the last one, because it costs nothing but attention — and it is the layer that decides how quickly a stolen unit can be identified as yours.
