Long periods of freezing weather, snow, wind and inactivity can damage water systems, batteries, seals and interiors. A winter storage plan combines mechanical preparation with periodic inspections.
Step-by-step guide
1. Plan the storage location
Confirm access, surface drainage, snow removal policies, security and any restrictions on covers, electricity or visits. Photograph the RV and record its condition before storage.
2. Prepare the water system
Follow your exact model’s winterizing procedure, including water heater bypass, low-point drains, pumps and appliances. Never assume that opening the taps alone protects every line.
3. Prepare the chassis and batteries
Check tire pressures cold against vehicle and tire guidance, inspect for leaks, follow battery maker storage instructions and arrange fuel-system or engine preparation according to the chassis manual.
4. Protect the exterior
Clean and dry the roof, inspect seals, retract awnings and slide-outs as specified, and remove debris from drains. Use a breathable, properly fitted cover only if suitable for the RV.
5. Close and document
Remove food and valuables, clean and dry the interior, protect against pests, record battery status and schedule periodic inspections after storms.
Common problems and what to check
| What you notice | Possible cause | Next step |
|---|---|---|
| Musty smell on return | Trapped moisture or unnoticed leak | Inspect roof, windows and interior before using heat to mask odours |
| Low battery voltage | Parasitic loads or poor storage charging | Follow battery maker guidance; inspect before recharging |
| Water below an RV | Drainage or plumbing issue | Determine source before reconnecting water |
Canadian winter considerations
Freeze-thaw cycles differ from coastal British Columbia to Prairie and northern climates. Heavy snow loads and ice accumulation require monitoring within the manufacturer’s roof-load and storage guidance.
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.

When should I start winterizing?
Before the first hard freeze, which varies by region.
