1. Pre-Season Caravan Preparation

Before your first trip of the season, thorough caravan preparation is crucial. This is especially important if your caravan has been in winter storage. Follow this comprehensive pre-season checklist to ensure your caravan is road-ready:

🔍 Exterior Inspection

  • Roof inspection: Check for cracks, damage, or sealant deterioration. Look for signs of water ingress around roof lights and vents.
  • Bodywork检查: Inspect for impact damage, stone chips, and paintwork condition. Address any rust spots immediately.
  • Seals and gaskets: Check all door, window, and roof seals for cracking or gaps. Replace worn seals to prevent water damage.
  • Awning: Extend fully and inspect for mould, tears, or mechanism issues.
  • Wheel arches: Check for debris accumulation and corrosion.

🛞 Tyre Safety Check

Tyres are your caravan's most critical safety component. Before every season:

  • Tyre pressure: Inflate to manufacturer specifications (usually 50-65 PSI for caravan tyres). Check cold.
  • Tread depth: Minimum 3mm recommended; replace if below 2mm.
  • Sidewall inspection: Look for cracks, bulges, or signs of UV damage from prolonged standing.
  • Wheel nuts: Check torque – should be 88-110 Nm for most caravans.
  • Corner steadies: Grease and check for wear.

⚡ Lights & Electrics

  • All lights: Test brake lights, indicators, tail lights, fog lights, and side lights with a helper.
  • 13-pin plug: Check for corrosion, bent pins, and secure connection.
  • Battery: Test voltage (should be 12.7V+ when fully charged). Clean terminals.
  • Consumer unit: Check circuit breakers and RCD functionality.

2. Water & Gas Systems Maintenance

Your caravan's water system and gas system require regular attention to ensure hygiene and safety. Whether you have a new caravan or a well-travelled model, these systems need proper maintenance.

💧 Fresh Water System

  • Flush regularly: Run fresh water through all taps monthly, even in storage.
  • Water heater: Descale annually using a propriety caravan water heater descaler.
  • Filters: Replace inline water filters every 6-12 months.
  • Wastes: Ensure waste pipes are clear; use non-toxic antifreeze in winter.
  • Thetford cassette: Clean regularly with proper cassette chemicals; replace seals annually.

🔥 Gas System Safety

The gas system in your caravan includes LPG cylinder storage, regulators, piping, and appliances. Safety is paramount:

  • Annual leak test: Have a qualified technician perform a pressure drop test annually.
  • Regulator: Replace every 10 years – check the expiry date on your current regulator.
  • Gas hose: Replace rubber gas hoses every 5 years (even if they look OK).
  • Appliance servicing: Have heating systems, fridges, and cookers serviced annually.
  • CO detectors: Replace batteries and test monthly; replace the detector every 5-7 years.
  • Ventilation: Never block ventilation openings – they're designed to prevent gas accumulation.

🧽 Cleaning & Hygiene

  • Shower tray: Clean with non-abrasive cleaners; check plug seal.
  • Upholstery: Vacuum regularly; clean fabric with appropriate caravan interior cleaners.
  • Windows: Clean seals with silicone lubricant to prevent drying and cracking.
  • Mould prevention: Ensure adequate ventilation; use moisture absorbers in storage.

3. Brakes & Suspension Maintenance

The braking system and suspension are arguably the most critical safety components of your caravan. Regular inspection and maintenance of these systems is non-negotiable for safe caravanning.

🛑 Brake System

  • Brake shoes/pads: Check annually; replace if worn below minimum thickness.
  • Brake drums/discs: Inspect for scoring, heat cracks, and wear patterns.
  • Wheel cylinders: Check for leaks and corrosion; replace if suspect.
  • Handbrake: Adjust so handbrake holds on a 1-in-3 slope; check cables for fraying.
  • Hydraulic fluid: Replace every 2 years or as per manufacturer guidelines.
  • Breakaway cable: Check condition; ensure it activates correctly. Replace if damaged.
  • Coupling head: Grease regularly; check for wear and proper engagement.

🔧 Suspension & Chassis

  • Axle: Inspect for cracks, especially near mounting points.
  • Springs: Check for broken leaves (leaf springs) or sag (coil springs).
  • Shock absorbers: Check for leaks and proper damping; replace in pairs.
  • Bushes: Inspect rubber suspension bushes for deterioration.
  • Jockey wheel: Grease mechanism; check clamp security.
  • Chassis: Inspect for rust, particularly in salt-affected coastal areas like Costa Brava.

⚠️ Important Safety Note

Brake work requires specialist knowledge. If you're not completely confident in your ability to safely maintain the brake system, always use a qualified caravan technician. Incorrect brake maintenance can result in brake failure – a serious safety hazard. At Punt Caravan Parking, our expert technician Lars offers professional brake inspections and servicing.

4. Winter Storage & Protection

For many caravan owners in Northern Europe, winter storage is a necessary part of ownership. Proper winter caravan storage protects your investment and ensures you're ready for the spring season. If you're storing your caravan in Spain at our Costa Brava facility, some of this advice still applies for extended periods of storage.

✅ Before Storage

  • • Clean inside and out thoroughly
  • • Remove all food and perishables
  • • Empty and clean fridge; leave door open
  • • Drain water systems; add antifreeze
  • • Fill fuel tank to prevent condensation
  • • Disconnect battery or use trickle charger
  • • Apply wax to exterior panels
  • • Cover tyres or use tyre savers

✅ During Storage

  • • Visit monthly to check condition
  • • Ensure ventilation is working
  • • Check for pest intrusion
  • • Look for signs of water ingress
  • • Run engine/towing vehicle monthly
  • • Keep battery charged
  • • Check tyre pressure monthly
  • • Inspect seals and door closures

5. Electrical System Care

Modern caravans rely heavily on electrical systems for comfort and convenience. Understanding and maintaining your caravan electrical system ensures reliable power whether you're on hook-up or touring.

🔌 12V DC System

  • • Battery condition monitoring
  • • Solar panel maintenance
  • • LED light efficiency checks
  • • Fuse box inspection
  • • USB charging port testing
  • • Alarm system function

⚡ 230V AC System

  • • Hook-up lead inspection
  • • RCD and circuit breaker testing
  • • Socket outlet condition
  • • Earth rod testing (if applicable)
  • • Appliance safety checks
  • • Inverter maintenance (if fitted)

🔋 Battery Maintenance

Your caravan battery is the heart of the 12V system. Proper battery care extends life significantly:

  • Type: Lead-acid batteries need checking; AGM and lithium require less maintenance but still need attention.
  • Voltage: Keep above 12.4V. Below this causes sulfation.
  • Trickle charging: Use a quality battery conditioner during storage.
  • Terminals: Clean and grease terminals annually.
  • Lifespan: Most caravan batteries last 4-6 years with proper care.
