In our regular Maintenance Matters column, industry expert Andrew Tapp (RV Inspections Ltd) shares his top tips and personal observations from 20+ years in the motorhome industry.
For motorhome owners, spring isn’t just a time to dust off the barbecue and plan road trips – it’s the perfect opportunity to give your RV a thorough health check.
Whether your motorhome has been parked up over winter or you’ve been using it year-round, the change of season is a reminder to ensure it’s in top shape before you head out on your next adventure.
There’s nothing like the confidence of knowing your RV is safe, functional, and ready for whatever New Zealand’s roads and weather throw at it. A spring health check means fewer breakdowns, lower repair bills (through early detection), and happier, safer travels. You don’t want to wait until you discover a problem such as a leak to show your motorhome some love.
And here’s the key: a proper spring health check isn’t something you can rush. Done properly, it takes time, care, and an eye for detail. To give you an idea, I usually spend two and a half hours on a full motorhome inspection.
Since starting RV Inspections Ltd almost 18 months ago, I’ve focused on doing pre-purchase inspections and water ingress testing, but increasingly, I’m seeing motorhome owners wanting a professional health check done.
It’s not just people buying or selling. Owners want peace of mind before the busy travel season begins, and they want to know they’ve covered all the bases. My Motorhome Health Checks are designed to give you, as the owner, a detailed, independent assessment of your RV’s condition.
Why a spring health check is essential
Spring is the ideal time for this kind of work. After winter, your motorhome may have:
- Been sitting unused for weeks or months
- Collected moisture inside and out
- Experienced battery discharge or fuel degradation
- Suffered from pests seeking shelter
- Developed small leaks, cracks, or component wear that you might not have noticed
In New Zealand, where the weather can swing from sunshine to sudden downpour in a matter of hours, ensuring your motorhome is road ready and weather tight is critical. Make sure you don’t leave your spring check until the week before you want to hit the road. Book early for any repairs or servicing needed and allow time to order in any required parts. Spring is a busy time for RV workshops – as an example, when I ran Platinum Motorhomes, by October, we would usually be booked out for the rest of the year.
Key elements of a spring health check
Here’s what I recommend as part of a comprehensive inspection.
1. Exterior Inspection – Weatherproofing and Structural Soundness
New Zealand’s mix of salt air, rain, UV exposure, and wind can be tough on your RV’s exterior. Start with:
- Roof & Seals: Check for cracks, gaps, or loose sealant around roof vents, skylights, antennas, and solar panels
- Windows & Doors: Inspect rubber seals for deterioration, ensure latches are secure, and test that everything opens and closes smoothly
- Body Panels & Paint: Look for damage, bubbling, or fading – signs of water ingress or UV degradation
- Chassis & Undercarriage: Examine for rust, loose bolts, or damage from road debris
- Awning: Extend fully to check for mould, tears, and correct operation
2. Moisture & Water Ingress Testing
Dampness is one of the most common – and costly – issues in motorhomes. Left unchecked, it can lead to rot, mould, and expensive structural repairs. This is why I use specialist equipment to test for hidden moisture in walls, floors, and ceilings. If I find early signs of ingress, owners can seal the problem area before it turns into a major job, after checking no further repairs are required.
3. Electrical Systems – Safety First
Electrical issues can range from inconvenient to dangerous. Check:
- House Batteries: Test voltage and capacity; check terminals for corrosion
- Mains Hook-Up: Inspect the cable and plug; test RCD operation
- 12V System: Test lighting, pumps, fans, and appliance circuits
- Solar Setup: Ensure panels are clean, wiring is intact, and the regulator is functioning
4. Gas Systems – Compliance and Safety
Gas leaks are serious business. Spring is the perfect time to:
- Check compliance certificates are up to date
- Inspect hoses and regulators for wear or cracks
- Test appliances (stove, oven, heater) for correct ignition and flame quality
- Ensure vents are clear and operational
5. Plumbing & Water Systems
After sitting unused, water systems can develop blockages, leaks, or bacterial growth.
- Flush & Clean: Empty and sanitise freshwater tanks
- Check Pumps: Test for smooth operation without airlocks
- Inspect Pipes: Look for leaks at joins, particularly around bends
- Waste Water: Empty and clean grey and black water tanks; check seals and valves
6. Appliances & Onboard Equipment
From your fridge to your heater, make sure all appliances:
- Operate correctly in all modes (gas, 12V, mains power)
- Are free of dust, insects, or obstructions in vents
- Have clean filters (especially in air conditioning units)
7. Interior – Safety & Comfort
- Smoke & Gas Detectors: Test batteries and operation
- Fire Extinguisher: Check date and pressure
- Seating & Sleeping Areas: Inspect for wear, tear, or damp
- Cupboards & Fixtures: Ensure nothing is loose or damaged from road vibration
8. Tyres, Brakes & Running Gear
- Tyres are your RV’s only contact with the road – don’t neglect them.
- Check tread depth and even wear
- Inspect sidewalls for cracks or bulges
- Confirm tyre pressures are correct for your load
- Test brake performance and check brake fluid levels
9. Engine & Mechanical (for motorised RVs)
Even if you’re not mechanically minded, you can:
- Check fluid levels (oil, coolant, brake fluid, transmission fluid)
- Look for leaks under the vehicle
- Listen for unusual noises on start-up
- Book in a mechanic for anything you’re not confident assessing yourself
Why a professional health check is worth it
It’s not just about finding problems – it’s about preventing them. A health check is an investment in your motorhome’s lifespan and your own safety. While many RV owners can and do carry out their own maintenance, a professional inspection offers several advantages:
Experience: A seasoned eye spots things you might miss
Equipment: Professionals will have specialist tools for moisture detection, gas leak testing, and electrical safety checks
Objectivity: An independent inspection gives you an unbiased view of your RV’s condition
Documentation: A written report is useful for insurance, resale, or warranty claims
Spring in New Zealand is a time of fresh starts. Make sure your motorhome gets one too. Whether you tackle the checklist yourself or bring in an expert, a thorough spring health check is your ticket to a safer, more enjoyable season of travel. Because on the open road, peace of mind is just as important as a full tank.
