Motorhome maintenance: Our guide to keeping your vehicle road ready all year round

However, you use your motorhome (cheeky getaways, rugged cross-country adventures or extended summer breaks) regular maintenance is important, to ensure it’s always ready to hit the road. Although domestic cars are complex machines, motorhomes take it to a different level as they include many systems that need your attention from time to time. Staying on top of these tasks can save you time, money and hassle and also ensure your safety – and comfort! – when you’re out on the road.

This edition of our blog features our top tips for keeping your motorhome in great condition. So, whether you’ve picked a new or used model from Chelston, these are the things that will keep it in peak condition.

Tyres are the only point where your motorhome and the road actually physically meet, so their upkeep is crucial. One of the most important things to keep an eye on is tyre pressure. Underinflated tyres can lead to premature wear, reduced fuel efficiency and even dangerous blowouts. Overinflated tyres can mean a harsh ride and they’ll cause uneven tread wear.

Check the tyre pressure regularly – especially before long trips, as their pressure can fluctuate with changes in temperature. It’s good to check them at least once a month and certainly before any journey. The correct tyre pressure for your motorhome will be detailed in the manual, or on a sticker just inside the door frame.

You should also inspect the depth of the tread, too. If it’s too shallow you should replace the tyres to ensure you get maximum grip on roads that are wet or slippery. Rotate your tyres regularly to ensure even wear, and inspect them for any punctures, cracks or bulges. If you find any issues, it’s always best to get your tyres checked by a professional before you take your motorhome out on the road.

Your motorhome’s engine and transmission are its heart, and they determine its performance. Keeping these essentials maintained means you’ll enjoy smooth operation – and it’ll also prevent costly repairs down the line. Check the engine oil, coolant and other fluid levels regularly, and make sure they’re within the recommended range. Set a regular service schedule, as keeping your engine well-lubricated and cool can extend its lifespan.

Oil changes are especially important. Engine oil degrades over time, losing its ability to lubricate and protect components. Follow the recommendation for oil change intervals for your vehicle (in general this is every 7,500 to 10,000 miles). Replace the oil filter each time as well.

Also pay attention to the air and fuel filters. If these are clogged it can hinder the engine’s performance and your vehicle’s fuel efficiency, so replacing them as part of routine maintenance is crucial. In addition, keep an eye on the engine belts and hoses as they can wear out, which could lead to engine failure if left unchecked.

Motorhome batteries are often tasked with running lights, appliances and other electrical systems when the engine is switched off – so a well-maintained battery is key. Start by checking the battery terminals for signs of corrosion and, if present, clean the terminals with a mixture of baking soda and water.

Test the battery’s charge on a regular basis, especially if you’re storing for an extended period. A battery that’s not in use can lose charge quickly, so it’s a good idea to disconnect during long periods of inactivity. If the motorhome has an auxiliary or leisure battery, check its charge and condition.

A Chelston technician can inspect and service your battery as part of our maintenance plans, available with flexible payment options.

The roof of your motorhome is constantly exposed to the elements, which makes it prone to dirt and dust, bird mess, moss and debris – and even wear and tear from UV rays. Regular inspections of the roof are vital to make sure there’s no damage that could compromise the structure of the vehicle. Check for any cracks, holes or signs of wear. Seal any minor cracks or gaps (with the appropriate sealant) to prevent water ingress. Clean the roof at least twice a year (or more often if you notice a build-up of grime) using a soft brush and non-abrasive cleaner. Be careful not to damage any seals or joints.

Motorhomes rely on their water systems for both hygiene and cooking needs, so it’s really important to keep the plumbing in good condition. Regularly check the motorhome’s water tank for any leaks, cracks or signs of wear. Make sure all the taps, shower head and pipework are free from blockages and damage.

It’s also crucial to sanitise your water system each year. Use a water-safe disinfectant to clean the water lines and prevent growth of bacteria and algae. This will ensure that the water coming out of your taps is safe to drink. You should also replace any worn-out filters. Lastly, make sure that the hot water system is working properly by checking the boiler (and related components). Flush the hot water tank periodically to remove any sediment build-up that could reduce efficiency.

Let a Chelston expert handle your roof and water system checks, with options for ongoing servicing on a convenient payment plan.

If your motorhome is equipped with a gas system for cooking or heating, regular safety checks are necessary. Inspect gas lines and connections for leaks. Replace damaged or cracked pipes immediately. A simple way to check for leaks is by applying soapy water to the connections and looking to see if there are any bubbles when the gas is turned on. If you have gas appliances like an oven or heating system, ensure they’re working correctly. It’s also a good idea to check your gas bottle and replace it if it’s old or damaged. Also replace the gas regulator if it shows signs of wear or corrosion.

Your motorhome’s electrical system controls everything – the lights, the refrigerator and the air conditioning, etc. To avoid electrical failures, inspect wiring and fuses regularly for signs of wear, corrosion or fraying. If you find any issues, immediately replace the affected parts. Check all the lights (interior and exterior), to make sure they’re working, and replace broken bulbs or faulty wiring to avoid being caught in the dark.

For hassle-free maintenance, Chelston professionals can check your gas and electrical systems, ensuring everything is safe and functional. Payment plans are available for added convenience.

Motorhomes face challenges during extreme weather, especially in winter when the temperatures drop right down. When it’s cold, it’s essential to drain water tanks and pipes to prevent freezing, as burst pipes can cause significant damage. Using antifreeze in the plumbing system will ensure water doesn’t freeze in the pipes. When the weather is much more temperate, you should make sure the vehicle’s cooling system is working properly. Check the air con and make sure your engine is not overheating.

Keeping the motorhome’s interior well-maintained and clean is just as important as looking after the mechanics. Use a vacuum cleaner, wash and wipe down and tidy up. Pay attention to upholstery, fabrics and surfaces, as spills can cause unsightly stains and long-term damage if they’re not cleaned up promptly. Inspect furniture and fittings for signs of wear and tear. Tighten any loose screws, replace worn-out cushions and make sure the beds, tables and storage compartments all work properly.
