how to store your trailer properly during harsh PA winters

Not using your trailer during the coldest months of the year? It’s important you still know how to properly protect and store your trailer during winter.

Let’s face it, Pennsylvania winters are tough on trailers. Between the freeze-thaw cycles, heavy road salt, and long stretches of cold storage, your equipment can take a beating if it isn’t prepped properly.

A little preparation now can save you costly repairs, inspection failures, and lost time once spring arrives.
Here’s a practical guide to keeping your trailer protected through the winter months.

Wash Away Road Salt Before Storage

Salt is your trailer’s worst enemy. If you park your trailer without a thorough cleaning, salt and grime can sit all winter, eating away at the frame and undercarriage. Use a pressure washer or high-volume hose to rinse the underbody, wheel wells, axles, and ramps. If possible, finish with a protective spray or wax coating to keep corrosion at bay.

Protect Your Tires from Flat Spots and Cracking

Cold weather and long storage periods can flatten tires and cause cracking. Inflate to the manufacturer’s recommended PSI before parking. If you have the option, place the trailer on blocks or move it slightly every few weeks to prevent flat spots. For trailers stored outdoors, use tire covers to block UV rays that accelerate rubber breakdown.

Disconnect and Store the Battery

Freezing temps drain batteries quickly. If your trailer has an electric winch or interior lighting, disconnect the battery and store it indoors in a dry, climate-controlled space. A trickle charger can keep it ready for spring use.

Secure the Brakes and Bearings

Moisture and salt are brutal on braking systems and wheel bearings. Grease your bearings before storage and check brake pads for wear. Parking on uneven or wet ground can also lock up brakes, so choose a flat, dry surface when possible.

Choose the Right Storage Spot

Where you store your trailer makes a big difference. A gravel or paved lot is far better than grass or dirt, which trap moisture under the frame. If you don’t have indoor storage, consider an enclosed trailer or high-quality cover designed to handle PA winters.

Quick Winter Storage Checklist

  • Wash off salt and grime
  • Check and inflate tires, cover if outdoors
  • Disconnect and store battery indoors
  • Grease bearings, inspect brakes
  • Park on gravel, pavement, or indoors
  • Use a quality trailer cover if exposed

Why It Matters in Pennsylvania

Unlike states with mild winters, Pennsylvania’s constant freeze-thaw cycles create harsh conditions for metal, rubber, and paint. Road crews use heavy salt, which speeds up rust far faster than rain alone. Skipping these steps may not show immediate damage, but by spring you could be facing frame corrosion, cracked tires, or failed inspections.

Prep Now, Save Later

A few hours of prep now can save hundreds in spring repairs or downtime. If you’re considering an upgrade, an enclosed trailer is one of the best defenses against PA winters.

FAQ

Why is it important to wash my trailer before winter storage?

Salt and grime left on your trailer over winter accelerate rust and corrosion, especially on the frame and undercarriage. A thorough wash protects your investment.

Can parking my trailer on grass or dirt damage it during winter?

Yes. Grass and dirt trap moisture under your trailer, leading to frame rust and brake issues. A paved or gravel surface is much safer.

How do I prevent my trailer tires from cracking or developing flat spots?

Inflate tires to the recommended PSI, move the trailer every few weeks, or use blocks to lift it slightly. Tire covers also protect against UV damage.

Should I remove the trailer battery for winter storage?

Yes. Freezing temps drain batteries quickly. Store the battery indoors in a dry, climate-controlled space and use a trickle charger if possible.

Do I need to grease bearings before storing my trailer?

Absolutely. Fresh grease protects bearings from moisture and corrosion during long storage periods. It also prevents unexpected breakdowns in spring.

What type of cover should I use for my trailer in Pennsylvania winters?

Choose a high-quality, weather-resistant trailer cover. Cheap tarps often trap moisture, leading to more harm than good.

Is indoor storage always better for trailers in winter?

Yes, indoor storage provides the best protection from salt, snow, and UV rays. However, if that’s not an option, proper prep and a good cover can still protect your trailer outdoors.

How often should I check my trailer during winter storage?

If possible, check monthly. Look for low tire pressure, signs of moisture, or rodent activity. Moving the trailer occasionally also helps prevent tire issues.

What happens if I skip winterizing my trailer in Pennsylvania?

You risk frame corrosion, cracked tires, battery failure, and costly spring repairs. Harsh freeze-thaw cycles and road salt make PA especially tough on trailers.

Are enclosed trailers better for winter storage than open trailers?

Yes. Enclosed trailers shield your equipment from snow, salt, and ice, making them a smart long-term investment in Pennsylvania’s harsh winters.
