The Ultimate Used Caravan Inspection Checklist

The Pre-Viewing Filter: Don't Waste a Journey

Before travelling to see a used caravan, whether it is a compact Swift or a luxury Bailey, ask the seller for specific documentation. A reputable seller should provide the CRiS (Central Registration & Identification Scheme) document and a recent habitation report from an Approved Workshop Scheme (AWS) technician. The AWS is a joint enterprise between the NCC (National Caravan Council), The Caravan and Motorhome Club, and The Camping and Caravanning Club, serving as the benchmark for touring caravan servicing in the UK.

Crucially, verify the Maximum Authorised Mass (MAM), also known as the MTPLM. The MAM is typically listed in the owner’s manual and shown on a plate or sticker fitted to the vehicle. According to DVSA Towing Regulations, the weight you are allowed to tow depends on when you got your licence. If you got your licence before 1 January 1997, you can usually drive a vehicle and trailer with a combined weight of up to 8,250kg MAM. If you got your licence from 1 January 1997, you can tow a trailer that weighs up to 3,500kg MAM. Use our towing calculator to match your outfit safely.

1. Exterior and Chassis Inspection

The exterior condition often reflects how well the previous owner maintained the internal systems. Start with the structural foundation by inspecting the chassis and running gear. The Approved Workshop Scheme notes that light leisure trailer servicing is vital for safety on the road.

Chassis and Running Gear

• The Hitch: Inspect the Al-Ko or Winterhoff hitch head. Check the wear indicator on the stabiliser pads and ensure the breakaway cable is not frayed or damaged. The breakaway cable is a critical safety component that applies the caravan brakes if it becomes detached from the tow car.
• Tyre Age: Caravan tyres rarely wear out their tread; instead, they perish from UV degradation and sidewall cracking. Check the 4-digit DOT code on the sidewall (e.g., 1224 means week 12 of 2024). The Caravan and Motorhome Club provides technical advice on caravan tyres and wheels, generally suggesting replacement every 5 to 7 years regardless of tread depth.
• Corner Steadies: Wind them up and down using the appropriate brace. They should move smoothly without grinding. Check the marine plywood floor around the steady mounting points for soft spots, which can indicate water damage or rot.

Bodywork Integrity

Walk around the van and look for "pimple" damp—small bubbles under the aluminium skin that indicate water is trapped behind the panel. Inspect the awning rails for gaps in the sealant or signs of DIY resealing. Check all windows for signs of delamination, where the two acrylic panes begin to split apart, or for internal condensation which suggests a failed seal.

2. The Damp Test: The Most Critical Step

Damp is a significant concern for leisure vehicles in the UK climate. You should always carry a pronged moisture meter when viewing a used caravan. Focus your checks on high-risk areas: around window frames, inside the front locker, under seat cushions, and around rooflights. Pay close attention to the wall-to-floor joints and the areas surrounding the door frame.

• 0-15%: Normal, dry condition.
• 15-20%: Requires monitoring; this suggests early signs of ingress that may need attention soon.
• Over 20%: Significant concern. This indicates a breach in the seals that requires professional investigation and resealing to prevent structural damage.

3. Internal Systems and Appliances

Replacing caravan appliances is expensive. Ensure the seller has the caravan connected to a 230V hook-up and has a gas bottle available for testing. The National Caravan Council (NCC) warns users never to use portable gas heaters indoors; ensure all fitted appliances are correctly flued.

• Gas Systems: Light all hob burners, the grill, and the oven. The flame should be steady and blue. Test the space heater and water heater on both gas and electric settings. If the caravan uses a Truma or Alde system, ensure it reaches temperature without error codes.
• Electrical: Check the RCD/MCB trips in the consumer unit. Ensure the 12V system works via the leisure battery. Check the status of the battery; the NCC maintains a Verified Battery List to help owners choose appropriate power sources. If the caravan has a motor mover fitted, ask for a full demonstration, as these are high-cost items to repair.
• Water: Run the pump and check every tap and the shower head. Look under the sinks and inside cupboards for leaks in the pipework. Check the toilet cassette seal for lubrication and ensure the flush mechanism operates correctly.

4. Paperwork and Provenance

Never buy a caravan without a CRiS check. This service, supported by the National Caravan Council (NCC), confirms if a caravan has been reported stolen, has outstanding finance, or has been written off by an insurer. You can learn more about this in our guide to CRiS checks and when to use them.

Check that the 17-digit VIN (Vehicle Identification Number) etched on the windows matches the number on the chassis plate and the CRiS registration document. Mismatched numbers are a major red flag for a stolen vehicle or a "ringer." Ensure the seller's ID matches the address on the CRiS document.

5. Used Caravan Market Considerations

Values vary based on caravan layouts and brand prestige. When browsing used caravans, consider that models with a full service history from an Approved Workshop are generally more desirable. The AWS scheme is the only one supported by all major UK manufacturers, ensuring that servicing during the warranty period is recognised.

Before finalising a purchase, ensure you have a dated receipt. If buying from a local dealer, clarify the terms of any warranty provided. Dealers often provide a 3 to 12-month warranty on used stock, which offers significant peace of mind compared to private sales.

Summary Checklist: The 10-Minute Walk-Round

1. Damp Meter: Check every corner, window seal, and rooflight.
2. VIN Match: Ensure windows, chassis, and CRiS logbook align.
3. Tyre DOT Code: Check for age; the Caravan and Motorhome Club suggests replacement every 5-7 years.
4. Floor Test: Walk the length of the van to check for "sponginess" or bounciness.
5. Service History: Look for annual habitation stamps from an AWS-approved workshop.
6. Appliance Test: Fridge, heater, and hob must be seen working on all power sources.
7. External Seals: Inspect awning rails and window rubbers for cracks or perishing.
8. Chassis: Check for excessive rust or damage to the A-frame and corner steadies.
9. Soft Furnishings: Lift cushions to check for mould, staining, or damp smells.
10. Road Lights: Ensure all indicators and brake lights function when hitched to a vehicle.
