1Exterior wash

• Wash the RV and roof with RV wash and a soft brush. Mould keeps growing if left.
• Clean the frame, undercarriage, wheel wells, tires and steps.
• Wash the awning and let it dry fully before rolling it up.
• Lubricate hinges, locks, slide-out gears and jacks. Treat all rubber seals.
• While you’re outside, make sure any propane tanks are turned off.

2Interior clean

• Vacuum and remove all food and crumbs, including in cushions.
• Remove toiletries that can freeze and split, like shampoo and toothpaste.
• Remove paper towels, tissues and rags that mice could nest in.
• Defrost and dry the fridge. Add baking soda and prop the doors open.
• Take valuables out of the RV and storage compartments.

3Line antifreeze

• Empty the black and grey tanks at a dump station. Flush the black tank if needed.
• Drain the fresh water tank and water heater, then bypass the heater.
• Pump RV antifreeze through every line, hot and cold, including the outdoor shower, toilet, ice maker and washer.
• Pour ½ cup of antifreeze into every P-trap.

4Mouse-proofing

• Fill holes underneath with expanding foam, caulking or wire mesh.
• Seal the power cord hatch and set mouse traps inside.
• Tip: A mouse fits through a hole the size of a pencil.

5Check and reseal

Cracked caulking lets water in, and the damage may not show until spring.

• Check roof seams, vents and antennas. Reseal with self-levelling sealant.
• Check windows, compartments, mouldings, doors and hatches. Reseal as needed.

6Moisture removers

Moisture damages the RV and helps mould and mildew grow.

• Place moisture removers inside. Ask us which ones we carry.

7Batteries

A drained flooded or AGM battery freezes quickly and will likely need replacing.

• Photograph the connections so you can hook them up the same way in spring.
• Confirm your battery type: lead-acid, AGM or lithium. Each type needs different winter care.
• Follow the battery manufacturer’s winter storage instructions, or see our RV Battery Winter Care sheet.

8Covers

• Use a breathable RV cover, never a tarp, to prevent mould and rust.
• Cover the tires with light-coloured, UV-resistant covers.
• Inflate the tires to their maximum cold pressure to prevent flat spots. In spring, lower them back to the RV’s driving pressure.

9Checking your RV

• Visit during storage. Refill moisture removers, check the traps and look for damage, leaks and flat tires.
