Why Regular Caravan Checks Matter

Regular Checks: Catching Problems Early – Your Comprehensive Guide to Caravan Maintenance

February 17, 2025

Maintaining a caravan is more than a chore—it’s a commitment to safety, longevity, and uninterrupted adventure. A single overlooked issue can turn a dream trip into a roadside nightmare. This guide expands on every critical checkpoint, offering detailed insights, practical solutions, and expert tips to ensure your caravan remains a reliable home on wheels.

Why Regular Checks Matter

Caravans face unique challenges: constant vibration, exposure to harsh weather, and the strain of mechanical systems. Neglecting maintenance can lead to:

  • Safety Hazards: Brake failures, tyre blowouts, or hitch detachments.

  • Costly Repairs: Undetected damp can rot walls; worn tyres damage suspension.

  • Trip Disruptions: Electrical faults or broken appliances mid-journey.

Proactive maintenance saves an average of £500–£1,000 annually in repair costs (Caravan Club UK, 2023). Start with these expanded checks:

1. Tyres: The Foundation of Safe Travel

Beyond Basics:

  • DOT Code Decoding: Locate the 4-digit code on the tyre sidewall (e.g., “3521” = 35th week of 2021). Replace tyres after 5–7 years, even with good tread.

  • Temperature Impact: Tyre pressure drops 1 PSI for every 5°C decrease. Check pressure before you tow, It’s a good habit to get into.

  • Step-by-Step Tyre Change:

    1. Park on flat ground, apply handbrake, and chock wheels.

    2. Loosen lug nuts slightly before lifting the caravan.

    3. Use a hydraulic jack rated for your caravan’s weight. Invest in a high-quality hydraulic jack and pair it with jack stands (e.g., 3-ton stands) for safe repairs. Practice lifting your caravan in a controlled environment before needing it in an emergency. For caravan-specific jacks, check brands like AL-KO, Milwaukee, or Norco—they’re trusted in the industry.

    4. Replace the tyre, tighten nuts in a star pattern, and torque to manufacturer specs.

  • FAQ

    Q: Can I use my car’s jack for my caravan?
    A: No! Car jacks are designed for lighter loads. Always use a jack rated for your caravan’s weight.

    Q: Why does my hydraulic jack sink over time?
    A: Worn seals or a faulty check valve may cause leaks. Replace parts or refill oil.

    Common Issues:

  • Flat Spots: Caused by prolonged storage. Roll the caravan slightly monthly to prevent.

  • Valve Stem Leaks: Apply soapy water; bubbles indicate leaks. Replace valve stems if damaged.

2. Lights: Visibility Equals Safety

In-Depth Tips:

  • Bulb Types: Halogen (common but energy-intensive) vs. LED (long-lasting, efficient). Upgrade to LED for better visibility and lower power draw.

  • Electrical Troubleshooting:

    • Flickering Lights: Check for loose connections or corroded wiring.

    • Fuse Box: Locate and label the fuses. Carry spares matching your caravan’s amperage. I keep a spares box in the caravan.

  • Cleaning Contacts: Use a wire brush or contact cleaner on corroded terminals.

Regulations: UK law requires all exterior lights to function. Fines up to £100 for non-compliance.

3. Brakes: Ensuring Control Under Load

System Types:

  • Overrun Brakes: Common in UK caravans; activate via tow vehicle deceleration.

  • Electronic Braking Systems (EBS): Advanced models adjust braking force automatically.

Testing Efficiency:

  • On-Road Test: In a safe area, brake sharply at 20 mph. The caravan should stop evenly without swaying.

  • Breakaway Systems: Test the HERE ; it should engage brakes if the caravan detaches.

Maintenance:

  • Brake Adjustment: Annual servicing includes adjusting shoe clearance and lubricating bearings.

  • Drum vs. Disc: Drum brakes are standard; disc brakes (premium models) offer better heat dissipation.

4. Hitch and Coupling: The Vital Connection

Hitch Types:

  • AL-KO Stabilizer Hitch: Reduces sway with friction pads. Replace pads every 2–3 years. They can be purchased online HERE and they are easy enough to replace. Check out YouTube for videos on how to do this.

  • Weight Distribution Hitches: Essential for heavier caravans; redistributes load to improve stability.

Pre-Journey Checklist:

  1. Clean the tow ball; grease attracts dirt that wears hitches.

  2. Secure safety chains in a crisscross pattern to catch the caravan if detached.

  3. Check and test the breakaway cable’s attachment to the tow vehicle, I always carry a spare in my car, you never know!

Lubrication: Use lithium-based grease on moving parts. Avoid over-greasing to prevent grime build up.

5. Corner Steadies: Stability When Parked

Types:

  • Manual: Crank-operated; affordable but labour-intensive.

  • Electric: Motor-driven; ideal for frequent use but pricier.

Maintenance Deep Dive:

  • Structural Checks: Inspect welds for cracks; loose steadies indicate frame damage.

  • Load Limits: Never exceed the manufacturer’s weight rating. Use levelling ramps to avoid overextending.

Pro Mistake: Using steadies to level the caravan strains the chassis. Always level with ramps first.

6. Windows and Doors: Securing Comfort

Seal Replacement:

  1. Remove old sealant with a plastic scraper.

  2. Clean the channel with isopropyl alcohol.

  3. Apply caravan-grade silicone sealant evenly.

Security Upgrades:

  • Lock Types: Standard latches vs. deadbolts. Fit anti-theft devices like Milenco handles.

  • Thermal Efficiency: Double-glazed windows reduce condensation and heat loss.

Draft Detection: Close all windows/doors, light incense, and watch for smoke movement. Seal gaps with brush strips.

7. Roof: Guarding Against the Elements

Material Care:

  • Rubber Roofs: Clean with mild soap; avoid petroleum-based products that degrade rubber.

  • Fibreglass: Polish annually with UV-resistant wax to prevent fading.

Repair Guide:

  • Small Cracks: Sand the area, apply fibreglass resin, and cover with matching paint.

  • Sealant Reapplication: Use products like Soudal Fix All for flexible, waterproof seals.

Insurance Note: Document roof inspections; insurers may deuy claims for pre-existing damage.

8. Dampness: Prevention and Cure

Advanced Detection:

  • Meter Types: Pin-type (accurate for localized spots) vs. capacitive (non-invasive for large areas).

  • Interpretation:

    • 0–15%: Safe.

    • 15–20%: Monitor closely.

    • 20%+: Immediate action required.

Repair Strategies:

  • Minor Damp: Dry with a dehumidifier, treat with anti-mould spray.

  • Major Infestation: Replace affected wood, reseal seams, and repaint with anti-damp primer.

Long-Term Prevention: Install roof vents with rain covers, use breathable caravan covers, and store in a dry, ventilated area.

Building a Routine: From Checklist to Habit

Sample Monthly Schedule:

  • Week 1: Tyres, brakes, hitch.

  • Week 2: Lights, electrics, appliances.

  • Week 3: Windows, doors, seals.

  • Week 4: Roof, damp check, corner steadies.

Digital Tools: Use Apps like Caravan Maintenance Log track inspections, set reminders, and store receipts.

Seasonal Tasks:

  • Spring: Check awning rails, service air conditioning.

  • Winter: Winterize plumbing with antifreeze, protect tyres with covers.
