As winter approaches, RV owners across Alberta begin preparing to tuck their vehicles away until spring. But when it comes to RV winter storage, success isn’t just about finding a parking spot — it’s about protecting your investment from freezing temperatures, moisture, and time.
Whether you’re planning winter trailer storage at home or using a trusted Diamond Valley storage facility, taking the right steps now can help prevent expensive repairs later. From maintaining your batteries to protecting your tires and draining your tanks, here’s how to properly prepare your RV for the winter months.
The Importance of Proper RV Winterization
Before anything else, you’ll want to complete a full RV winterization. This process protects your plumbing system, tanks, and water lines from freezing and cracking when temperatures drop. Neglecting this step can lead to leaks and costly damage in spring. Start by consulting your owner’s manual for your specific travel trailer or motorhome.
Each model may have slightly different steps, but the basics are always the same: drain, clean, and protect. Most storage facilities that offer winter storage near Calgary or in Diamond Valley can recommend or even assist with winter storage prep — giving you peace of mind that your vehicle is safe through the coldest season.
Step 1: Take Care of the Battery
Your RV battery is one of the first components affected by cold weather. When temperatures dip below freezing, the charge capacity drops significantly, leading to sulfation and reduced lifespan. Before storing, disconnect your batteries completely. If possible, remove them and keep them indoors where the temperature stays above freezing.
Make sure each one is fully charged — partial batteries charge levels can lead to permanent damage over time. If you’re storing at a facility that offers RV storage with electrical hookups, you can leave your battery on a maintenance or trickle charger. Many storage solutions in Alberta now include power access as part of their facility offers.
Step 2: Protect Your Tires
When an RV sits still for months, tire damage is a real concern. Long-term pressure on the same contact patch can cause flat spots, and the cold can make rubber stiff and brittle. Before long term storage, clean your tires thoroughly to remove dirt and road salt.
Inflate them to the recommended PSI and check for cracks or wear. If your RV will remain parked outdoors, use tire covers to protect against UV rays and snow.
If possible, move the RV slightly every few weeks or use leveling blocks to shift weight off the tires. In some storage facilities, staff may even assist with checking tire covers or inflation during your storage experience.
Step 3: Drain and Protect the Tanks
One of the most critical steps in RV winterization is draining the water system. Start by emptying your fresh water tank, grey water tank, and black water tank. Open all faucets and low-point drains, then use the RV’s water pump to push out remaining water.
Next, bypass your water heater and add RV antifreeze to the plumbing lines. Run the antifreeze through every faucet and fixture until the pink liquid appears, confirming your lines are protected. Even if your RV is parked in heated storage facilities or inside a storage unit, it’s still smart to properly winterize — unexpected cold snaps can damage plumbing quickly.
Step 4: Choose the Right Storage Facility
Not all storage options are created equal. When looking for winter storage near Calgary, choose a location that provides security, accessibility, and proper environmental protection. Reputable facilities, such as those offering Diamond Valley storage, often include wide driveways for easy parking, on-site staff, and both indoor and outdoor units.
If you plan to store your RV outside, make sure the area is well-drained and protected from direct snow buildup. For the best storage experience, consider a facility that offers covered or enclosed spots, especially if you plan on long term storage through the coldest months.
Step 5: Inspect and Seal Before Storing
Before your RV goes into storage, walk around the exterior and check for any cracks, gaps, or loose seals. Pay special attention to roof seams, windows, and storage compartments. Reseal any damaged areas to prevent moisture from seeping in over winter. Inside, clean thoroughly and remove all food or perishables. Prop open the fridge and freezer, and leave cabinet doors slightly ajar to encourage airflow. The goal is to keep your RV cool, dry, and pest-free until spring.
Step 6: Give It a Final Check
Once everything is prepped, give your RV one final inspection before you close it up. Confirm that batteries are disconnected, tires are inflated, tanks are drained, and RV antifreeze is properly circulating through your lines.
Label any maintenance items that will need attention before next season — such as oil changes, filter replacements, or tire rotation — so you can hit the ground running when it’s time to travel again. If you’re using storage facilities like those near Diamond Valley or Calgary, ask staff if they perform periodic checks on stored units. Knowing your RV is safe and maintained gives you that extra peace of mind.
Step 7: Relax Until Spring
With your winter trailer storage handled, you can relax knowing your RV is secure, dry, and protected. When the snow melts and adventure calls again, you’ll be ready to hit the road without worrying about cracked pipes, dead batteries, or flat tires.
