How to prepare your RV for storage
There’s an art to storing an RV that will see it last for years of holiday service. It’s not a dark art, it’s mostly common sense, but there are some things that could easily be missed and might cause issues when you next need your van.

Whether a person spends $5000 on a camper or $110K on a caravan, it’s still an investment worth looking after, with best practice being to maintain the van in tip-top condition all year round so that it takes no time to get it ‘road ready’ when a trip is in the offing.


To achieve this ideal requires some serious thought and a plan. A checklist that kicks into place after a trip is a great idea to ensure nothing is forgotten.


Spend a few hours at the carwash or in your driveway and clean the van from top to bottom and underneath, and dry thoroughly. A good polish or wax will prepare the exterior for storage and make it easier to wash off the dust prior to heading away again.

Book the van in for a complete mechanical check with a registered and approved repairer. Most of us home mechanics can do brakes and lights and other things but checking for cracks in the chassis, worn bushes or other structural body problems may need an expert.

A crucial safety check of the gas lines and cylinders will ensure your van doesn’t leave the postcode you left it in

The mechanic can also grease the underneath of the van for you, which will spare you from completing this essential task.

A recommendation from Andrew Phillips from the RV Repair Centre was to deal with any rust found around the A-frame or bumpers to prevent this eating away at your investment while stored.

Shut down the gas system and burn off any gas in the lines. This should be off during travel anyway but we all know of people who flaunt that rule.


While the biggest clean job is the exterior, the interior should also be cleaned from top to bottom and be totally dry before going into storage.

There are two thoughts on bedding. One is to leave bedding out of the van until it’s needed.
The other is to clean and replace bedding ready to go on short notice. Either works and if you place a moisture absorber tub in the van, it will reduce the chance of mould due to climatic conditions and keep the bedding fresh.

Close all windows and blinds. This prevents UV damage if stored in the sun and also stops critters from nesting in the window frames.

De-frost and clean the fridge and freezer and leave the fridge doors open. Some vanilla essence in a lid or small jar will keep the fridge smelling sweet and bi carb will help draw away any moisture and also absorb smells.

Insect nests in your window frames – perish the thought? Close the blinds


Water tanks should be drained if the van is being left for six months or more. Leave the drain open and use a gauze filter to prevent bugs nesting inside. If the van is being used more regularly, keep the tanks full but flush before use if the water tastes or smells funny.

While many people head away for winter, if a van is stored where it could freeze then it’s recommended the water is drained from the hot water service. If this is not done, check the anode pre and post travel, including draining the tank and replacing any stale water in the system.

Cassette toilets require a thorough clean once emptied. Once clean enough to eat your dinner off, pop a little water and chemical in the bottom to keep it fresh ready for storage.

Grey and black tanks are fairly common these days. These tanks need to be emptied and flushed thoroughly to avoid nasty smells and germs.

Washing machines should be clean and dry, including the lint filters, before storing. We’d also recommend leaving the lid open.

HANDY HINT! If you want to avoid chemicals, a solution of vinegar and water will clean black and grey water tanks


Make sure everything electrical is working properly including lights and major appliances and repair anything that needs it. Switch the van off at the main power switch to ensure all power is shut down.

Today’s modern electrical systems are pretty clever, which makes storing a van easier, although keeping the batteries charged will depend on where the van is stored and what’s available to charge them. Disconnecting batteries either mechanically or physically is the safest solution although the battery will still discharge slowly over time.

If the van is stored at a site where there is no way to charge the battery, it’s best to remove and take them home where the charge can be maintained correctly.

If solar or 240V power is available, use an appropriate charger to maintain the batteries. Most appliances run clocks and other things where if a light’s on there is a power drain. The right charger will allow the battery to drain slightly then recharge for maximum life. Using products such as an Ampfibian is a safe way to manage 240 volts into a van during storage as well as travel.

Chris McClellan, Director of Enerdrive, explained that lithium technology is expanding but the same rules apply with regard to keeping batteries charged correctly. The big difference with lithium is that if you murder the battery by allowing it to go flat, it’s going to cost a lot more to replace so a 240V or solar system set up correctly is a good way to go.

Remember, a van stored in a garage or under cover may get light on a solar panel but if it’s not direct sunlight it may take more power to operate the system than it’s receiving, leading to a flat battery.

HANDY HINT! If you can go into the van once a week and use power for a few hours then charge the battery back up, this will help maintain the battery. They do like to be discharged and recharged for a longer service life


There are many options for storing vans. The best one is undercover in a garage or shed where it’s not in direct sunlight and there’s power to keep things charged.
The next best is under a carport where extra protection may be required to ensure the van stays in top shape. The last and least desirable is out in the open.

In the past, people would jack up a van and rest it on chocks to avoid flat spots on tyres which made life hard if you wanted to get away in a hurry. These days the recommendation is to park the van on a flat surface and pump the tyres up to the max tyre pressure to avoid flat spots. Don’t forget to drop the tyre pressures down before heading out again.

Tyres should be covered to prevent UV damage. A board or heavy waterproof sheet can be used for this.

Use a good rust proofer or lubricant on stabilising legs and anything that might rust shut. Ant Sand around the wheels, stabilising feet and jockey wheel will prevent ants and other bugs crawling inside. This needs to be checked regularly to maintain the protection. You may wish to consider the issue of rodents, too, as the damage they can do is considerable.

Caravan covers are a popular storage accessory, but they need to be secured properly to avoid them flapping around and causing damage to the body. If a cover isn’t used then a bucket can cover the hitch and wiring plugs from the weather. The gas bottles and regulator also need to be covered with a secured tarp.

Depending on the storage space some people will leave the handbrake off to avoid rusting of the shoes and magnets, especially if the van has just been washed. If this is the case chock the wheels to prevent the van from wandering but leaving the handbrake on is preferable.

Gas or diesel heaters will have a vent to the exterior of the van. Ensure these covers are closed and sealed properly. If there is a van-mounted generator then cover the exhaust with a bag or similar to prevent wasps and bugs getting in.


There is a real concern for stored vans when it comes to insurance claims. Read your policy and ensure the right coverage is in place.

Points of difference include undercover versus outside storage as well as storage at home versus in a registered storage facility. Having anti-theft gear such as wheel clamps, hitch clamp or even an alarm system may help lower the insurance bill.

NOTE: Fire Safety

Do you have a fire plan for your van or camper? Living in a bush fire-prone area requires some thought as to how a van or camper is stored. If you want to take your van off-site with you if there is a fire, make sure the details are included in your fire plan. This will make getting hooked up under stressful conditions easier.
