Seasonal Caravan Maintenance Tasks for Spring and Autumn

Spring: Waking Your Caravan After Winter Storage

Few moments beat that first spring trip. Before you hitch up, though, the van needs a proper once-over. Winter is kind to neither sealant nor water systems, so set aside a full day and work through the job methodically rather than rushing it the morning you plan to leave.

Start outside. Walk a full circuit and look closely at the bodywork, paying particular attention to the roof seams, awning rail, window rubbers and around the rooflights. Sealant hardens over time and hairline cracks let water in. Clean the mastic line with a mild detergent, let it dry, then reseal anywhere that looks suspect.

Next, check for damp inside. A cheap moisture meter is one of the best investments a tourer owner can make. Press the probes into the corners of the floor, under the windows, beneath the front lockers and around the shower tray. Readings above roughly 15 to 20 per cent mean you should investigate further before the season gets going. Deal with a small leak now and it stays small.

Spring: Water, Gas and Electrical Systems

The water system is the usual source of spring headaches, so flush it properly before you use anything.

Drain and flush. Empty any residual water, refill the system with a proprietary sterilising solution, run it through every tap and the shower, then leave it to stand as directed on the bottle before rinsing thoroughly.
Check the pump and hot water. Bleed the system with all taps open until the flow is steady and free of spluttering. Test the heater on gas and electric if you have both.
Gas hoses. Look at the date stamp on flexible hoses — replace them every five years regardless of appearance. Do a bubble test on the connections with soapy water and never use a naked flame to hunt for leaks.
Battery. A leisure battery that sat unused for months will likely need a good slow charge on a smart charger. Test the voltage once charged and check the terminals for corrosion.
Electrics. Confirm the road lights, indicators, brake lights and fog lamps all work — ideally with someone standing behind the van.

Spring: Running Gear and Tyres Before the First Tow

Tyres are the single most neglected safety item on a tourer. Because they sit still for long periods, they perish rather than wear. Look for cracking in the sidewalls and check the four-digit date code — anything over five to seven years old should be replaced even if the tread looks ample.

Inflate to the pressure recommended for your van's laden weight, not the pressure printed on the car. Check the spare too, and make sure you have a working jack and brace aboard.

Then work along the running gear: the coupling head should engage smoothly and lock positively, the stabiliser pads should still have material on them, and the breakaway cable should be undamaged and correctly routed. Test the overrun brake and handbrake, and listen for rumbling wheel bearings on your first run out — if you are unsure, a pre-season service by a qualified technician is money well spent.

Autumn: Winterising the Water System

Frost is what kills caravan plumbing, and a single hard night can split a pipe or crack a pump housing. Empty everything before the first frost of the season, not after.

Drain fully. Open all taps and the drain valve, empty the water heater, and leave the taps in the open position over winter.
Clear the pipes. Blow residual water through with a hand pump or drain-down kit, or introduce a food-safe antifreeze suitable for caravan water systems.
Toilet and tanks. Empty the flush tank and cassette completely, and clean both before storage so nothing dries on.
Waste containers. Tip, rinse and store them upside down with the caps off.

Autumn: Protecting the Bodywork, Interior and Battery

Give the van a thorough wash and let it dry completely, then apply a wax or protective polish. Pay attention to the front panel, which takes the brunt of road spray, and clean out the awning rail channel so debris does not trap moisture against the sealant.

Inside, remove anything that could attract damp or pests. Cushions should stand on edge rather than lie flat, the fridge door should stay propped open, and cupboards should be wiped out and left ajar. Vacuum thoroughly — crumbs are an invitation. Leave a roof vent cracked open on its lowest setting and place moisture traps around the van, checking them through the winter.

The leisure battery should come out if possible, or be connected to a maintenance charger. Store it somewhere frost-free and top it up every month or so. If you leave it in place, disconnect the negative terminal.

Finally, resist the temptation to store the van on its corner steadies. Raise the wheels off damp ground where you can, or at least move the van slightly every few weeks and over-inflate the tyres to guard against flat spots. A breathable cover is worth the outlay; a plastic tarpaulin is not, as it traps condensation against the paintwork.

Booking Your Pre-Season Service

If you do one thing each year, book a habitation service in late winter. An approved workshop will check the gas system, damp readings, electrics and running gear in a couple of hours, and it keeps you right with most insurance policies. Combine that with the checks above and your caravan will be ready to roll the moment the weather turns kind — and tucked up safely when it does not.
