Winter Trailer Maintenance: What You Need to Know
29, Mar, 2025
Winter can be tough on trailers, with cold temperatures, moisture, and road salt causing wear and tear. You’re storing your trailer for the season or using it in winter conditions, proper maintenance is essential to prevent damage, ensure safety, and extend its lifespan.
Protect the Trailer from Rust and Corrosion
Moisture and road salt can lead to rust, so it’s important to take preventive measures. Wash your trailer thoroughly before winter, removing dirt and salt buildup. Applying a protective wax or rust-proof undercoating will help prevent corrosion. If you’re storing it outdoors, try to keep it on dry ground like concrete or gravel rather than grass or dirt, which can trap moisture.
Keep Tires in Good Condition
Cold temperatures cause tire pressure to drop, which can lead to blowouts if not checked regularly. Inflate your tires to the recommended PSI and inspect them for cracks or dry rot. If your trailer will be parked for long periods, consider moving it occasionally to prevent flat spots or use tire cradles.
Check the Electrical System
Brakes and hinges can freeze in cold temperatures, leading to safety hazards. If your trailer has air brakes, be sure to drain the air tanks regularly to remove moisture. Lubricate axles, hinges, jacks, and couplers with cold-weather grease to keep everything moving smoothly. If locks are exposed to the elements, apply a de-icer spray or graphite lubricant to prevent freezing.
Winterizing Water Systems (If Applicable)
If your trailer has water tanks or plumbing, winterizing is necessary to prevent frozen pipes. Drain all water tanks, including fresh, gray, and black water tanks. Use RV antifreeze in the water lines and insulate exposed pipes if you plan on using the trailer in freezing conditions.
Proper Winter Storage
If you’re storing your trailer for winter, find a covered location like a garage or barn to protect it from the elements. If outdoor storage is the only option, use a high-quality, breathable trailer cover to prevent snow buildup. Remove the battery and store it separately, and use wheel chocks instead of engaging the brakes to avoid wear.
Final Thoughts
Taking care of your trailer in winter ensures a longer lifespan, better performance, and fewer costly repairs. A little effort now can save you a lot of trouble when spring rolls around!
