At a glance: A spring startup checklist for plumbing, batteries, tires and safety equipment.

After winter storage, the RV needs a deliberate inspection before occupants use water, propane, electrical equipment or the road. Spring startup is also the best time to find storage-related damage.

Safety first: Never energize an empty water heater or ignore a suspected propane leak. Always follow the RV, chassis, appliance and equipment manufacturers’ instructions.

Seasonal RV care is a cycle: inspect, prepare, check periodically, and test before returning to the road.

Step-by-step guide

1. Inspect exterior and chassis

Look for roof damage, seal failures, pest activity, tire deterioration, brake concerns and leaks before moving the RV.

2. Restore plumbing per manual

Follow the RV and water-heater instructions to remove winterizing product, return bypass valves to service positions, flush and sanitize the potable system as specified.

3. Restore electrical systems

Inspect battery condition and charger compatibility before connecting shore power. Test GFCI devices and safety alarms according to instructions.

4. Check appliances safely

Verify vents are clear, inspect visible propane components and arrange qualified service for suspected gas or combustion problems.

5. Perform a controlled test trip

Check lights, brakes, hitch components, wheel condition, fluid levels and all essential systems before a long trip.

Canadian winter considerations

Spring thaw can expose freeze-damaged fittings, especially after extreme winter lows. Some Canadian roads impose seasonal weight restrictions; check local transport advisories.

Check local forecasts, provincial road information and storage facility rules before you travel or work outdoors. Conditions vary widely between the Pacific coast, the Prairies, Atlantic Canada and the North.

Recordkeeping and follow-up

Save dated photographs, service receipts, product labels and inspection notes. Note any unresolved problems so they can be inspected before the RV returns to service. Where procedures involve gas, high-voltage electricity, structural repairs or vehicle lifting, use a qualified technician.

Spring inspection

Wait for reliably above-freezing nights, inspect for cracks and leaks as you restore water, and check roof, seals, tires and battery before the first trip.
