Preparing your motorhome for Summer 2026

Now that the days are growing longer and the weather's finally cheering up, motorhome enthusiasts can finally start thinking about their next adventure. But before you set off, a bit of basic prep could make every trip smoother and safer.

Whether you’re a seasoned camper‑on‑wheels or gearing up for your first proper summer on the road, these practical checks and simple habits will get your motorhome ready for the season ahead. Let’s get started!

1. Give your motorhome a deep clean

Winter storage leaves all sorts behind: dust, stale smells, and the odd surprise in places you forgot existed. Work through the interior first and check the main spots: under seats, inside cupboards, and the storage bins that gather crumbs over winter.

Once the inside feels fresh, give the exterior a good wash. Grime builds up quietly, and rinsing it away makes it easier to spot cracks, loose fixings, or seals that need attention. By the time you’re done, you will have a much clearer idea of what your motorhome needs before summer trips begin.

2. Look out for water damage and leaks

Seals can stiffen over winter, so a quick walk around the motorhome will show you how they have held up. Windows, doors, roof vents, and any joints along the roofline deserve a closer look because these areas often let water sneak in when you least expect it.

Inside the van, pause in the places that tend to hide trouble. Storage lockers, overhead cupboards, and corners where the walls meet the ceiling sometimes show the first signs. Damp patches, soft spots, a bit of mould, or a faint discolouration all tell you that moisture has found its way in. Catching it now saves you dealing with swollen timbers or musty smells later in the season.

3. Give your batteries a health check

Batteries sit quietly through winter, but they can still lose charge even if disconnected. Before you fire everything up for summer, give yours a quick once-over. A visual check goes a long way because bulging sides or small cracks tell you the battery has had its day and needs replacing.

After that, grab a voltmeter and see how much charge is left. Anything below 12 volts means it’s ready for a top-up. No one wants a flat battery just before a big summer trip!

4. Check tyres and brakes

Cold weather takes its toll on tyres. When your motorhome sits still for weeks, the pressure drops and the rubber stiffens, which affects how the van handles once you’re back on the road.

Look over each tyre for cracks, worn patches, or anything that doesn’t look quite right. Then grab a pressure gauge and make sure every tyre is properly inflated to the recommended level (including the spare). Even one underinflated tyre will affect how the motorhome steers and stops.

While you’re there, test the brakes too. A short run on a quiet stretch of road will tell you whether they feel sharp and responsive or a bit sluggish after winter. Better to sort it now than discover it when the motorhome is fully packed for holiday season.

5. Check the engine and fluid levels

Engines don’t like being ignored, especially after a long winter, so it’s worth having a quick look under the bonnet. Start by checking the essential fluids:

Oil reservoir
Engine coolant
Windscreen washer fluid
Battery & brake fluid

Some reservoirs are transparent, so you can see the levels at a glance. Coolant and windscreen washer fluid usually sit in clear containers, making it easy to top them up if they look low. Oil needs a different approach. Pull out the dipstick, give it a quick wipe, then check the level again to make sure it sits where it should.

6. Test your ventilation and air conditioning

Warm weather makes good airflow a priority, so it’s worth checking everything now while the motorhome is still parked up. Switch on the air conditioning first and see how quickly it cools the cabin. If it feels weak or takes ages to settle, the system may need a service. Have a quick look at the air filter too, because a clogged one will slow everything down and make the unit work harder than it should.

Don’t forget to check your windows and air vents too. Open each one, make sure the seals are intact, and check that they move freely. Fresh air does wonders after months of being closed up, so let the breeze run through the van and clear out any lingering stuffiness.

7. Test your electrical and gas appliances

Once the batteries are topped up, it’s worth giving the whole electrical setup a quick once-over. Start by inspecting the fuses, cables, and any visible connections. Frayed wiring or loose fittings will cause headaches later, so catching them now saves you fiddling about halfway through a trip.

When everything looks sound, hop inside and run through your appliances one by one. Try the interior and exterior lights, then check that the fridge, stove, and heating systems all spark into life as they should. Propane-powered kitchen appliances deserve a quick test too, since they sometimes need a minor tweak after sitting idle for months. If you’re at all unsure, consult an expert.

Lastly, if you use solar panels, give them a clean to clear away grime and check the wiring. Clean panels charge faster after all!

8. Restock supplies and organise

It’s a good idea to restock the essentials before summertime. Here’s what’s worth thinking about:

Toilet chemicals
Propane
Fire extinguishers
First aid supplies
Kitchen and bathroom kits

Once your supplies are sorted, you could also invest in some new storage solutions. Collapsible containers make clever use of tight spaces, and labelled storage bins can help you find things quickly when you’re halfway through setting up camp. A bit of organisation now will make your home on wheels feel easier to live in once summer adventures begin.

9. Update your documents

Before you start planning routes and campsites, have a quick look through your paperwork. Make sure your insurance, MOT, and road tax are all up to date and ready for the season ahead. As for insurance, it’s worth checking your cover still suits the kind of trip you’re planning and considering any extra protection you might need.

Final thoughts

Summer trips always feel better when the motorhome is ready for the miles ahead, and a bit of prep now saves you chasing small problems once you’re on the road. So, pencil in some time on the weekend to tick off the basics, and picture where the first journey of the year might take you. A well‑looked‑after motorhome always rewards you with an easier, more relaxed adventure.
