Used campervan inspection checklist that actually helps

Quick Answer:

• Verify the V5C: Check the 'Body Type' and VIN. Note that DVLA requirements for 'Motor Caravan' status are strict; many conversions remain classed as 'Van' but must be declared to insurers.
• Damp is the Priority: Use a pinless damp meter around windows and seals. Readings above 20% indicate structural risk.
• Safety First: Verify gas systems meet BS EN 1949 standards and check tyre DOT codes; replace if over 5-6 years old.
• System Test: Run all appliances (fridge, heater, taps) for 15+ minutes to ensure they don't fail under load.

Buying a used campervan is a strategic way to secure a high-spec vehicle while avoiding the steep depreciation of a new model. However, the complexity of modern conversions—featuring lithium power, solar arrays, and intricate plumbing—means a casual walk-around is no longer sufficient. In 2026, a systematic inspection is your best defence against inheriting a 'money pit'.

Whether you are viewing a factory-built Volkswagen California or a bespoke conversion from Vanworx, this guide uses evidence from the NCC and DVLA to ensure your purchase is safe, legal, and roadworthy.

1. The Paperwork & Legal Audit

Before inspecting the hardware, you must audit the software—the documentation. Discrepancies here can invalidate insurance or lead to legal issues with the DVLA.

• V5C Logbook: Check the 'Body Type'. According to the DVLA, you must update the V5C for changes to seating capacity, weight, and body type. Many modern conversions are described by the DVLA based on external appearance; if it still says 'Panel Van', ensure your insurer is fully aware of the internal fit-out.
• Service History: Leisure vehicles often have low mileage but suffer from 'standing' issues. Look for annual oil changes and brake fluid flushes, regardless of miles driven.
• Habitation Certificates: Ask for a report from an Approved Workshop. This should include a gas tightness test and a full damp report.
• Weight Compliance: Overloading is a common legal trap. Use our Motorhome Weight Checker to calculate if the remaining payload can handle your gear, water, and passengers.

2. Exterior & Chassis Integrity

A campervan's exterior is its first line of defence against the British weather. Any breach here leads to rot.

• The Roof & Seals: Inspect the sealant around solar panels and skylights. The Caravan and Motorhome Club notes that roof lights are prime candidates for leaks. If it is a pop-top, check the canvas for mildew and the lifting struts for fluid leaks.
• Tyre Safety: Check the sidewalls for the 'DOT' code. TyreSafe.org warns that tyres should be replaced every 5 to 7 years, even if the tread looks deep, as the rubber perishes over time. Look for 'CP' (Camping) rated tyres, which are designed to handle the higher pressures required for heavy, static loads.
• Base Vehicle Health: Check for rust on the sills and wheel arches. For a deeper dive into which chassis to choose, read our guide on base vehicles explained.

3. Habitation & Conversion Quality

A high-end finish can sometimes hide poor structural work. You need to verify the 'bones' of the build.

• Cabinetry & Fixtures: Perform a 'shake test' on all units. They should be securely fixed to the vehicle's internal framework. Check that all 'rock and roll' beds have appropriate safety pull-test certification if they are intended for travel use.
• Damp Testing: This is non-negotiable. Use a moisture meter to check the floor, especially under the kitchen unit and around the wheel arches. Any reading consistently above 20% suggests active water ingress that requires professional repair.
• Gas Safety: Ensure the installation complies with BS EN 1949. There must be a sealed gas locker with a 'drop-out' vent to allow escaping gas to exit the vehicle safely. Check the Gas Safe Register recommendations; hoses should typically be replaced every 5 years.

4. Electrics, Water, and Heating

Replacing a faulty electrical system or a seized diesel heater can cost thousands. Test them under load.

• Electrical Systems: Switch on all lights and the fridge simultaneously. If the voltage on the control panel drops significantly, the leisure battery may be end-of-life. If you are looking at different layouts, ensure the battery location is accessible for maintenance.
• Water Systems: Fill the fresh tank and run the taps. The pump should prime and then shut off. If it pulses or continues to run, there is a leak or a pressure fault. Check the waste tank for secure mounting and easy drainage.
• Heating: Fire up the diesel or gas heater. It should reach maximum temperature within 10 minutes without excessive smoke or 'locking out'.

5. The Test Drive

A campervan drives differently than a standard van due to the permanent high centre of gravity.

• Cold Start: Always insist the engine is cold. A warm engine can mask issues with glow plugs or fuel injectors.
• Braking & Suspension: Listen for groans or knocks when cornering. Heavy conversions put immense strain on factory suspension; many owners upgrade to heavy-duty components to improve stability.
• Transmission: On popular models like the Volkswagen Transporter, check for smooth shifts in DSG gearboxes and no 'clutch judder' in manuals.

Frequently Asked Questions

What should I look for when buying a used campervan?

Prioritise a damp-free shell, a documented service history for the base vehicle, and a valid habitation certificate. Ensure the conversion is safe, with proper gas venting and fused electrical circuits.

Does the V5C have to say 'Motor Caravan'?

Not necessarily. The DVLA has strict external aesthetic requirements for the 'Motor Caravan' classification. Many high-quality conversions remain 'Van' on the V5C. The critical factor is that your insurance policy explicitly covers the vehicle as a campervan conversion.

How often should campervan tyres be changed?

According to TyreSafe.org, tyres should be inspected annually after five years and replaced by the sixth or seventh year, regardless of tread depth, due to UV degradation and internal carcass fatigue.

Can I check for damp without a meter?

While you can look for staining, 'pinking' of wallboards, or a musty smell, these are signs of advanced damage. A pinless moisture meter is the only way to detect early-stage ingress before it becomes a structural failure.

What is a habitation service?

It is a comprehensive safety check of the living area, covering gas tightness, 230V/12V electrical safety, water system integrity, and a full body damp test. It is recommended annually by the NCC.

Is a DIY conversion safe to buy?

It can be, provided the seller can produce a Gas Safe certificate for the LPG installation and evidence that the electrical system was installed to leisure vehicle standards. If in doubt, factor the cost of a professional inspection into your offer.
