Used Motorhome Buying Checklist: What to Check Before Buying
QUICK NAVIGATION
A second-hand motorhome can look immaculate yet have hidden damp, worn mechanical parts or faulty living-area equipment. Before buying, check the vehicle's identity and history, inspect its body and systems, and take a proper test drive. This checklist explains what you can assess yourself and when to ask a specialist to investigate.
1. What Should You Check Before Viewing a Used Motorhome?
Start with the documents and basic specifications, not the photographs. A few questions can prevent a wasted journey to view a motorhome that is overweight for your licence, unsuitable for your family or missing important maintenance records.
What Information Should You Ask the Seller for in Advance?
Request the registration number, make, model, year, mileage and a photograph of the vehicle's weight plate. Ask for dated engine-service invoices, habitation and damp reports, plus details of any leaks, accident damage or major repairs. If the seller cannot supply these, clarify what is missing before arranging a viewing.
How Can You Check the MOT History of a Motorhome?
Use GOV.UK's free MOT history service to compare recorded mileage, failed tests and recurring advisories with the seller's account. Repeated tyre, brake or corrosion advisories deserve further investigation even if the latest test was passed. An MOT assesses roadworthiness at the time of the test; it does not certify the habitation equipment or confirm that the body is damp-free.
Does the Layout and Payload Meet Your Needs?
Count designated belted travel seats separately from sleeping berths, and check bed access, washroom space and the vehicle's height and length. Compare the plated maximum authorised mass (MAM) with a recent actual weight, allowing for passengers, water, luggage and fitted accessories; also check individual axle limits. GOV.UK's motorhome driving rules state that driving a motorhome over 3,500kg and up to 7,500kg normally requires category C1 entitlement.
2. How Do You Check a Motorhome for Damp and Water Damage?
Water ingress can damage insulation, floors and hidden structural components long before obvious stains appear. Inspect the vehicle in daylight, ask when it was last tested for damp and do not treat a fresh interior smell or newly applied sealant as proof of a sound body.
Where Should You Look for Water Ingress?
Examine rooflight surrounds, roof-to-wall joints, window frames, door seals and any holes made for aerials, solar cables or accessories. Inside, check corners, under mattresses, around the shower, beneath sinks and along floor edges; open exterior lockers and inspect their lower corners. Look for repairs or inconsistent sealant along the same areas from outside.
What Are the Signs of Damp in a Motorhome?
Warning signs include dark marks, bubbling wall covering, swollen timber, soft flooring, a persistent musty smell and rusty fasteners. Press gently around suspicious edges rather than forcing panels, and photograph any defect. A dry-looking surface can still conceal water damage behind furniture or wall coverings.
Should You Ask for a Professional Damp Test?
Yes, particularly on an older coachbuilt motorhome or one with any history of leaks. Ask a motorhome workshop for a dated, location-by-location report using suitable moisture-testing methods, with photographs and an explanation of abnormal results. A single meter reading is not a diagnosis: materials, temperature and testing technique affect interpretation. The NCC-backed Approved Workshop Scheme confirms that its motorhome habitation service includes a damp check and report.
3. What Mechanical and Safety Checks Should You Make?
Treat the engine and chassis as a separate inspection from the living accommodation. Mechanical faults can be costly even when the habitation area is in excellent condition, so arrange a qualified inspection if anything safety-critical is uncertain.
How Do You Check the Engine, Gearbox and Brakes?
Compare service invoices with the manufacturer's maintenance schedule, including cambelt replacement where applicable. On a cold start, watch for persistent warning lights, unusual smoke, fluid leaks or abnormal noises; during a permitted test drive, check smooth gear changes and even braking. Do not accept an explanation for a dashboard warning without a diagnosis.
How Do You Check Motorhome Tyres and Suspension?
Check tyre size and load rating, tread, sidewall cracking, bulges and the manufacture date code, including the spare. Low mileage does not prevent tyre ageing, particularly on vehicles stored for long periods; TyreSafe's motorhome guidance recommends inspecting ageing damage and obtaining professional advice if in doubt. Uneven wear, a sagging corner or visible suspension leaks warrant further checks.
What Should You Look for on a Motorhome Test Drive?
With the correct insurance and licence entitlement, drive at urban and open-road speeds, checking steering, braking, gearbox response and engine temperature. Listen for rattles from the cab and living area, and watch for warning lights or the vehicle pulling to one side. Try reversing and parking to make sure its dimensions suit you.
4. How Do You Inspect the Habitation Area and On-board Systems?
Ask the seller to demonstrate each system rather than simply saying it works. Check equipment on its intended power source, record any failures and leave electrical or gas testing that involves dismantling to a competent professional.
How Do You Check a Motorhome's Electrical System?
Operate the 12V lights, control panel, water pump and fitted accessories; check that the leisure-battery display responds when charging is demonstrated. Where safe and available, confirm mains hook-up powers the relevant sockets and charger, and ask for records of previous electrical work. Damaged wiring, overheating or unexplained tripping calls for an electrician's assessment.
How Do You Check the Gas, Heating and Cooking Systems?
Ask for service records and a safe demonstration of the hob, heater, hot water and gas-powered fridge functions, where fitted. Check the condition and accessibility of gas lockers and visible hoses without disconnecting anything. GOV.UK's Gas Safe guidance explains that paid gas work must be performed by a registered professional; confirm the engineer is qualified for the relevant LPG leisure-vehicle work.
How Do You Check the Water System and Washroom?
With the tank filled sufficiently for testing, run every tap, check hot and cold water, flush the toilet and watch that sinks and shower drains empty properly. Inspect beneath fittings and around the pump for drips, staining or softened surfaces. Ask whether the system was drained and protected against freezing during winter storage.
What Interior and Exterior Fittings Should You Inspect?
Open every locker, test hinges, blinds, flyscreens, windows and doors, and make up each bed to confirm the cushions and mechanisms are complete. Extend the step and awning only with the seller's assistance, checking for damage and smooth operation. Make a written list of broken fittings and missing accessories before agreeing a price.
5. What Documents Should You Check Before Buying a Used Motorhome?
Match the paperwork to the actual vehicle and keep copies of the advert, inspection reports and agreed sale terms. The registration certificate identifies the registered keeper; it does not, by itself, prove legal ownership.
How Do You Verify the V5C, VIN and Seller Details?
Compare the VIN stamped on the vehicle with the V5C log book and confirm the registration details through GOV.UK's used-vehicle checks. Ask why the seller's identity or address differs from the registered keeper and request evidence of their right to sell. Police guidance also confirms that a V5C is not proof of ownership.
How Do You Check Service and Habitation History?
Look for dated invoices showing the registration or VIN, work completed and the garage or workshop responsible. Separate engine and chassis servicing from habitation reports, gas and electrical work, damp checks and repairs to seals or body panels. If a warranty depends on annual inspections, verify that the required dates and conditions were met.
Should You Check for Outstanding Finance or Theft Records?
Yes. A paid vehicle-history check can flag recorded outstanding finance, theft markers, insurance write-offs and mileage discrepancies that an MOT record alone will not reveal. Citizens Advice's used-vehicle guidance recommends obtaining such a check; resolve any finance entry with documented settlement before paying.
6. What Questions Should You Ask the Seller of a Used Motorhome?
Ask these questions directly and keep the answers in writing:
Has the motorhome ever suffered water ingress, damp repairs or accident damage?
When were the engine, chassis and habitation systems last serviced?
Which appliances, accessories or functions are faulty or not currently working?
What equipment is included in the sale, and which additions were fitted later?
What are the plated maximum weight, current actual weight and usable payload?
What written warranty, deposit, repair or return terms apply to this sale?
What Are the Red Flags When Buying a Used Motorhome?
Walk away from an unexplained VIN mismatch, suspected stolen-vehicle records, undisclosed serious water damage or a refusal to allow a reasonable independent inspection. Be cautious about missing invoices, unresolved safety warnings and pressure to pay immediately. With a dealer purchase, written terms and the Consumer Rights Act 2015 matter; private sellers generally do not provide the same statutory consumer remedies.
7. Should You Get a Used Motorhome Inspected Before Buying?
Yes, especially for a high-value purchase, an older coachbuilt vehicle, a private sale or any motorhome with incomplete records. Independent reports can identify problems missed during a viewing, but they cannot guarantee that every concealed fault will be found.
What Does an Independent Motorhome Inspection Cover?
Book the checks you actually need: a mechanical inspection for engine, chassis and road safety; a habitation inspection for living-area systems; and a damp survey for potential water ingress. Confirm in writing whether the inspector will road-test the vehicle, test gas and electrics, assess underbody corrosion or examine inaccessible areas. An Approved Workshop Scheme motorhome habitation service covers the living area, not engine servicing or a full mechanical assessment.
What Should You Do If the Inspection Finds Problems?
Obtain written repair estimates and decide whether the seller will complete the work before handover or reduce the price accordingly. Do not drive a vehicle with unresolved safety-critical defects; arrange professional repair first. If serious damp, structural damage or unclear ownership cannot be resolved, leave the purchase.
