It’s common for motorhomes to sit unused for weeks or even months, particularly over winter. While motorhomes are built for travel, long periods of inactivity can lead to unexpected issues if they’re not prepared properly. Understanding how long a motorhome can sit unused and what problems may arise, helps you avoid costly repairs and start the season with confidence.
So, how long is too long? The answer depends on how the vehicle is stored and maintained.
The Short Answer
Most motorhomes can safely sit unused for 4–6 weeks without issue. Beyond that, especially after 2–3 months, the risk of problems increases unless preventative steps are taken. Batteries discharge, seals dry out, fluids deteriorate and mechanical components can begin to suffer from lack of use.
Common Problems Caused by Long Periods of Inactivity
Battery Drain
Starter and leisure batteries can lose charge surprisingly quickly when a motorhome isn’t in use. Once fully discharged, batteries may not recover, leading to replacement rather than a simple recharge.
Tyres and Brakes
Tyres can develop flat spots when left in the same position for long periods and brakes may seize or bind, particularly in damp conditions.
Damp and Water Ingress
Lack of ventilation and temperature changes increase the risk of condensation and damp. Small leaks can go unnoticed while the motorhome is parked up, becoming serious problems by the time it’s used again.
Engine and Mechanical Issues
Engine oil can degrade over time, seals may dry out and components that rely on movement can stiffen. Diesel fuel can also deteriorate if left for long periods without use.
LPG, Water and Habitation Systems
Water systems may stagnate, pipes can freeze in cold weather and LPG components such as regulators and hoses may deteriorate over time if not checked.
How to Store a Motorhome Safely for Long Periods
If you know your motorhome will be off the road for a while, a few simple steps can help reduce the risk of problems:
- Keep batteries charged or use a maintenance charger
- Slightly move the vehicle periodically to avoid tyre flat spots
- Ventilate the interior to reduce condensation
- Drain water systems if storing in winter
- Check tyre pressures and fluid levels regularly
Taking these precautions can significantly extend the time your motorhome can sit unused without issues.

What to Check Before Using Your Motorhome Again
After a period of storage, it’s important to carry out basic checks before heading off:
- Battery condition and charging systems
- Tyres, brakes, and suspension
- Engine oil and fluid levels
- LPG gas system operation
- Water system cleanliness and leaks
A professional inspection can help identify hidden issues that aren’t always obvious at first glance.

When to Get a Professional Check
If your motorhome has been unused for several months or longer or if you notice warning signs such as warning lights, strange noises, damp smells or poor performance, it’s best to have it checked before travelling. Catching issues early can prevent breakdowns and ensure your first trip back on the road is stress-free.
At Bristol Caravans, we regularly help owners get their motorhomes safely back into use after winter storage or long periods of inactivity.
Get Back on the Road With Confidence
Leaving a motorhome unused is sometimes unavoidable, but it doesn’t have to lead to problems. With the right preparation, regular checks, and professional support when needed, you can protect your vehicle and enjoy worry-free travel all year round.
If you’re unsure about the condition of your motorhome after a period of storage, having it inspected before your next trip can give you peace of mind and help you start the season the right way.
