Motorhome Maintenance Tips to Prevent Expensive Repairs

1. Inspect Seals, Roofs & Windows for Water Ingress

Water damage is one of the most common (and costly) issues in motorhomes. Even a small leak can lead to rot, mould, and electrical failures. 

Top Tips: 

• Check all window and roof seals for cracks, gaps, or soft spots every few months.
• Reseal or replace seals as soon as you notice signs of wear.
• Consider professional damp checks annually.

2. Pay Attention to Tyres, Even When Parked

Motorhomes often sit idle for weeks or months, which can lead to tyre damage or flat spots.

Top Tips: 

• Check tyre pressure regularly and inflate to the recommended PSI.
• Inspect tread depth and sidewalls for cracking or bulges.
• Rotate tyres if the motorhome is parked long-term, or move it occasionally to avoid flat spots.

3. Look After Your Battery & Electrical System

Nothing kills a holiday vibe like a flat battery. When not in use, motorhome batteries can discharge over time—especially in colder weather.

Top Tips:

• Disconnect the leisure and engine batteries when storing the vehicle.
• Use a trickle charger or solar panel to maintain battery health.
• Check all fuses, lights, and sockets for proper function before a trip.

4. Maintain the Engine and Chassis - Even With Low Mileage

Motorhomes may cover fewer miles than everyday vehicles, but engine oil, filters, and brake components still degrade over time.

Top Tips:

• Stick to the manufacturer’s recommended service intervals.
• Change oil and filters annually, regardless of mileage.
• Get the chassis checked for rust, alignment issues, and brake wear.

5. Keep it Clean - Inside and Out

A clean motorhome is more than just a pleasure to travel in—it helps extend the life of your paintwork, seals, and interior fittings.

Top Tips:

• Wash the exterior regularly, especially after trips to the coast or countryside.
• Wax annually to protect against UV and moisture damage.
• Clean and air out the interior to avoid condensation and mildew.

6. Store it Safely During the Off-Season

Improper storage is a major cause of damage in the winter months.

Top Tips:

• Store under cover or use a breathable motorhome cover.
• Drain water tanks and insulate pipework to prevent freezing.
• Leave internal doors and lockers ajar to encourage airflow.
