A caravan that has carried you through corrugated tracks, coastal camps and long stretches of highway deserves more than being parked behind the shed and forgotten. Knowing how to prepare a caravan for storage protects the systems that make touring comfortable, helps prevent expensive surprises, and means you can hitch up with confidence when the next escape calls.
The right approach depends on whether your caravan is stored for a few weeks, a full off-season, or several months between big trips. A secure, dry spot is the starting point, but water, battery care, tyres, seals and pests all need attention before you lock the door.
How to prepare a caravan for storage
Start while you are still unpacking from your last trip. It is far easier to spot a loose fitting, wet canvas item or stone damage when the journey is fresh in your mind than it is three months later. Give yourself enough time to clean, inspect and dry the van properly rather than rushing through the job on departure day.
Empty, clean and dry every living space
Remove food, rubbish, toiletries and anything with a strong scent. Even sealed packets can attract ants, rodents and insects, while forgotten pantry goods can spoil in the heat. Empty cupboards and drawers where practical, then wipe them out and leave them dry.
Clean the fridge, switch it off and prop the door open so air can circulate. A closed fridge is one of the quickest ways to create mould and unpleasant odours. Empty the microwave, check under seat bases and lift removable mats to make sure sand, crumbs and moisture are not trapped where you cannot see them.
Soft furnishings need attention too. Let bedding, towels, annex walls and awnings dry completely before packing them away. If the caravan has been through wet weather, leave windows and doors open while you clean, provided the area is secure, until every surface feels dry. Moisture trapped inside a closed caravan can damage upholstery, timber finishes and electrical connections over time.
Drain the water system
Fresh water left sitting for extended periods can develop odours and contamination, while trapped water can cause damage if temperatures drop in colder regions. Drain the fresh water tanks according to the manufacturer’s instructions, empty grey water tanks, and run the taps until the lines are clear.
Do not forget the hot water system. Isolate its power source, allow it to cool, then drain it as directed in the owner’s manual. If your caravan will be stored for a long period, follow the manufacturer’s recommended process for sanitising the system before your next trip.
Empty the cassette toilet and clean it thoroughly. Leave the toilet area dry and ventilated. A few minutes spent here makes a big difference when you return to the van.
Protect batteries and off-grid electrics
Your electrical system needs a considered approach, especially in an off-grid caravan with lithium batteries, solar input, an inverter and multiple charging sources. Switch off non-essential 12V loads, including lights, pumps, entertainment systems and accessories that may create a small but constant draw.
Battery storage requirements vary by chemistry and system. Many lithium battery systems are best stored at a partial state of charge rather than left full or allowed to run flat. Check the battery manufacturer’s guidance and your caravan manual before deciding whether to leave the solar system connected, use a maintenance charger, or isolate the battery completely.
If the caravan is stored under cover with limited sunlight, do not assume the solar panels will keep up with background loads. A quality charger with an appropriate storage mode may be the better option, but only where safe power and the correct equipment are available. Inspect battery terminals for corrosion, make sure cables are secure, and test smoke alarms and carbon monoxide alarms before closing up.
Disconnect 240V power once the battery plan is sorted. Check that exterior power points, solar connections and cable hatches are clean, dry and closed against dust and insects.
Check tyres, brakes and the undercarriage
Tyres can lose pressure slowly while a caravan sits, particularly through changing temperatures. Inflate them to the pressure recommended for your tyre and load setup, then inspect sidewalls and tread for cuts, cracking, embedded stones and uneven wear. If your caravan will be stationary for months, moving it occasionally can help reduce flat spotting.
Where practical, store the caravan on a firm, level surface rather than grass or bare dirt. Moisture rising from the ground can encourage corrosion beneath the van, and soft ground can allow wheels to sink. Purpose-made wheel ramps or pads can help spread the load and keep tyres out of standing water.
Use wheel chocks securely. Avoid relying only on the handbrake for long-term storage, as brake components can bind after extended periods. The best method varies with your site and caravan braking system, so follow the manufacturer’s instructions and make sure the caravan cannot roll before releasing any brake.
While you are underneath, inspect the chassis, suspension, brake wiring, stone guards and recovery points. Remove mud, salt, grass seed and road grime, particularly after coastal travel or off-road touring. Australian-made strength starts with good engineering, but regular cleaning is what helps protect that investment over the long haul.
Give seals, roof and exterior fittings a close look
Wash the exterior with a caravan-safe cleaner and allow it to dry. Pay close attention to the roof, window frames, hatches, awning rails, checkerplate and the areas around external lights. Dust and leaf matter hold moisture against surfaces, while bird droppings can mark paintwork if left in place.
Inspect sealant around windows, roof penetrations, vents and service hatches. Look for splits, gaps, lifting edges or signs of water staining inside the caravan. Do not simply apply new sealant over a problem area without identifying the cause. A small leak can become a major repair if it is left through a wet season.
Lubricate locks, hinges, jockey wheel components and coupling parts with products suitable for those materials. Clean and lightly protect the coupling, then fit a cover if appropriate. Ensure the breakaway cable, chains and electrical plug are off the ground and protected from weather and pests.
Keep pests and weather out
Close all windows, roof hatches and external access doors, but avoid sealing the caravan so tightly that moisture has nowhere to go. Internal ventilation is useful when the caravan is clean and dry. Moisture absorbers can assist in humid areas, although they need regular checking and replacing.
Rodents can enter through remarkably small gaps. Check around plumbing entries, cable openings, fridge vents and underbody penetrations. Remove nesting material from the drawbar area and keep vegetation trimmed back from the caravan. Avoid using poisons inside the van, where an inaccessible dead rodent can create a far worse problem than the one you started with.
A roofed carport or shed offers the best weather protection, provided there is adequate clearance and ventilation. If outdoor storage is the only option, choose a breathable cover designed for caravans and secure it carefully. Cheap plastic tarps can trap condensation, rub through paintwork and conceal water leaks. In some locations, regular washing and inspection may be more effective than covering the caravan at all.
Secure it without making access difficult
Use a quality coupling lock, wheel clamp or both, depending on where the caravan is stored and your insurance requirements. Remove valuables, spare keys, portable electronics and personal documents. Photograph the caravan inside and out, including accessories and identifying details, then keep the images with your insurance records.
Before you walk away, make a short storage note with the date, battery status, tyre pressures and any maintenance jobs you noticed. Set a reminder to inspect the caravan every four to six weeks. A quick check for water ingress, battery condition, tyre pressure and pest activity is far easier than repairing months of unnoticed damage.
When adventure season returns, your pre-storage effort will show in the small things: a fresh-smelling interior, healthy batteries, tyres ready for the road and a caravan prepared to head beyond the blacktop again.
