Spring Awakening: De-Winterizing Your Trailer and Moving Equipment

Winter's over. The temperature is climbing, the roads are clear, and you're ready to get your trailer back in action. But before you hitch up and head out, there's work to do. A trailer that's been sitting dormant for months needs attention before it's road-ready. Skip the de-winterizing process and you're setting yourself up for breakdowns, damage, and wasted weekends dealing with problems that could have been prevented.

Here's how to properly bring your trailer and moving equipment out of winter storage.

Start With a Visual Inspection

Walk around the entire trailer before you do anything else. Look for obvious damage that might have occurred during storage. Cracked seals, damaged siding, dents, anything that wasn't there when you put it away. Check for signs of rodent activity like chewed wires, nests, or droppings. Mice love to set up shop in stored trailers, and they can do serious damage.

Check the roof for cracks, peeling, or areas where water might have gotten in. Inspect the undercarriage for rust and corrosion. Salt, moisture, and freeze-thaw cycles are hard on metal components. Surface rust is manageable, but structural rust needs immediate attention.

Check the Tires and Bearings

Tires sitting in one spot all winter develop flat spots, lose air pressure, and can crack from temperature changes. Check the pressure on all tires, including the spare. Inflate them to the recommended PSI.

Inspect the tread for uneven wear, cracks in the sidewall, or signs of dry rot. If your tires are more than six years old or showing significant wear, replace them before you hit the road. Check the lug nuts and make sure they're torqued properly.

Wheel bearings need grease to function properly. If they sat all winter without use, that grease may have settled or dried out. Pull the wheels, inspect the bearings, and repack them with fresh grease. If you don't know how to do this yourself, have a mechanic handle it. Bad bearings can seize up while you're towing, which can cause wheel lockup or complete failure.

While you've got the wheels off, check the brakes. Look at the pads or shoes for wear and make sure the brake lines are intact.

Test the Lights

Hook the trailer up to your tow vehicle and test every light. Running lights, brake lights, turn signals, all of it. Moisture can get into light housings during winter and corrode the connections. If a light isn't working, check the bulb first, then the wiring. Clean any corroded connections with a wire brush and dielectric grease.

Flush and Sanitize the Water System

If you winterized your plumbing with RV antifreeze, you need to flush it out completely. Open all the faucets, flush the toilet, and let everything drain. Fill the fresh water tank with clean water and run it through all the lines several times until the water runs clear with no pink tint.

After flushing, sanitize the fresh water tank. Mix a quarter cup of bleach per 15 gallons of tank capacity. Fill the tank with this mixture, let it sit for at least 12 hours, then drain it completely. Refill with fresh water and flush through all the faucets again until there's no chlorine smell.

Charge or Replace the Battery

Batteries lose charge over winter even if they're disconnected. If you stored your battery on a trickle charger, it should be ready to go. If not, charge it fully before use.

Check the battery terminals for corrosion. Clean them with a wire brush and a mixture of baking soda and water. Apply dielectric grease to prevent future corrosion. If the battery is more than three to five years old or won't hold a charge, replace it.

Lubricate Moving Parts

Anything that moves needs lubrication, especially after sitting idle all winter. Hitch, jack stands, stabilizer jacks, slideouts, door hinges, latch mechanisms, all of it. Use the appropriate lubricant for each part.

Don't forget the trailer dolly if you use one. Lubricate the hitch connection, the wheels, and any moving mechanisms. Test it to make sure it's functioning properly before you actually need to use it.

Inspect Propane System

If your trailer uses propane, check the entire system before you fire anything up. Look at the lines for cracks or damage. Check all connections for tightness. Use a soap and water solution to check for leaks. Spray it on the connections and look for bubbles. If you see bubbles, fix the leak before you use the system.

Test your propane appliances one at a time. The stove, water heater, furnace, fridge if it runs on propane. Make sure they all ignite properly and run without issues.

Clean and Organize

Open up the trailer and air it out. It's been closed up for months and probably smells stale. Open windows, turn on vents, and let fresh air circulate.

Clean everything. Wipe down surfaces, sweep floors, clean the fridge and freezer. Check cabinets and storage areas for signs of pests or moisture damage. Restock supplies that you emptied before winter storage.

De-Winterize Your Trailer Dolly

If you use an electric trailer dolly, check the battery. Charge it fully and verify it's holding a charge. If the battery is several years old or showing signs of weakness, replace it.

Inspect the wheels and tires on the dolly. Make sure they're inflated properly and not showing cracks or damage. Test the dolly by moving a trailer a few feet to confirm everything is working smoothly. Clean off any dirt, salt, or debris that accumulated during storage.

Test Everything Before You Need It

Don't wait until you're loading up for your first trip to discover something's not working. Run through all the systems now. Turn on the water pump and check for leaks. Fire up the furnace and AC. Test the fridge on both electric and propane. Make sure the awning extends and retracts properly.

Check your emergency equipment. Fire extinguisher, smoke detector, carbon monoxide detector, first aid kit. Replace batteries, check expiration dates, and make sure everything is functional.

Take a Short Shakedown Trip

Before you commit to a long trip or head somewhere remote, take a short shakedown trip close to home. Spend a night or two at a nearby campground and actually use the trailer. This gives you a chance to identify any problems in a low-stakes situation where you can easily return home or get help if needed.

Pay attention to how the trailer tows. Listen for unusual noises. Check for vibrations or handling issues. Inspect the hitch connection after the first 50 miles to make sure nothing's come loose.

Remember Your Wheel Chocks

As you're getting back into the routine of using your trailer, remember that wheel chocks are essential safety equipment. Any time you unhitch the trailer, chock the wheels. When you're using a dolly to reposition the trailer, especially on any kind of slope, chock the wheels before and after moving. A runaway trailer is preventable with a simple set of chocks.

Bottom Line

De-winterizing a trailer takes time, but it's not optional. Winter is hard on equipment that's sitting idle, and assuming everything will work fine just because it worked last fall is how you end up stranded with preventable problems.

Walk through each step methodically. Inspect, clean, lubricate, test, and fix anything that's not right. Do it now and your trailer will be ready for a full season of use. Skip it and you'll be dealing with breakdowns and repairs when you should be enjoying your time on the road.

Spring is here. Your trailer should be too.
