How to Prepare a Trailer for Long-Term Storage

Whether you're a weekend traveler, a contractor, or a recreational enthusiast, your trailer is an investment worth protecting. When it’s time to store your trailer for the off-season or a longer stretch, it’s not as simple as parking it and walking away. Improper storage can lead to flat tires, rust, water damage, and even rodent infestations.

At Allen Drive Open Storage in Conroe, TX, we specialize in providing reliable outdoor trailer storage and secure trailer storage systems for all types of trailers. To help you get the most life out of your trailer, we’ve put together a complete guide on how to properly prepare it for long-term storage, whether you're using a trailer storage container or open-space options.

Let’s dive into the essential steps you should follow to keep your trailer in peak condition while it’s off the road.

1. Clean the Trailer Inside and Out

One of the most overlooked, yet most important, steps in long-term trailer storage is a thorough cleaning. Residues like road salt, bird droppings, and grime can cause corrosion or staining if left for long periods.

Exterior Cleaning:

• Use a non-abrasive soap and soft-bristle brush to scrub the trailer exterior.
• Rinse thoroughly, especially underneath, to remove dirt and road debris.
• Dry completely to prevent moisture damage.
  

Interior Cleaning:

• Remove all food items and perishables to avoid attracting rodents.
• Sweep floors, wipe down surfaces, and empty all compartments.
• For RV or travel trailers, clean the refrigerator and leave the door ajar to prevent mold.
  

This cleaning process not only maintains your trailer’s appearance but also prevents long-term damage from contaminants, pests, and moisture buildup.

2. Maintain Tires and Suspension Components

Tires take the brunt of long-term storage issues, often developing flat spots or dry rot. If left unchecked, your trailer could be unsafe to tow when it's time to use it again.

Tips for Tire and Axle Protection:

• Inflate tires to the manufacturer’s recommended PSI.
• Use tire covers to guard against UV rays, especially in outdoor trailer storage.
• Place wood blocks or jack stands under the frame to take the weight off the tires.
• Avoid parking on soft surfaces like grass or dirt, which can retain moisture and promote rot.
  

Also, grease the wheel bearings and inspect the suspension system for any signs of wear or corrosion before storage.

3. Disconnect and Store Batteries Properly

For trailers that contain electrical systems, battery maintenance is key during long-term storage. Batteries lose charge over time and can become damaged if left connected and unattended.

Battery Storage Guidelines:

• Disconnect the battery cables to prevent slow discharge.
• Store the battery in a dry, cool location — ideally off the ground and inside a climate-controlled space.
• Consider using a trickle charger or battery maintainer if the trailer is being stored for more than a few months.
  

Neglecting the battery can result in corrosion, reduced performance, or total battery failure, so it's worth taking these small steps to preserve it.

4. Drain Fluids and Protect the Plumbing

For RV and camper trailers that have water systems, it’s critical to drain all tanks and lines. Standing water can freeze, mold, or cause unpleasant odors over time.

Plumbing & Fuel System Prep:

• Drain freshwater, gray water, and black water tanks completely.
• Flush lines with non-toxic RV antifreeze if storing in colder climates.
• Add a fuel stabilizer to the gas tank and run the engine for a few minutes to circulate it, if applicable.
• Lubricate hinges, slide-outs, and jacks to prevent sticking and corrosion.
  

These maintenance steps will protect internal systems from the effects of disuse and environmental exposure, especially when using trailer storage systems for seasonal offloading.

5. Secure, Cover, and Choose the Right Storage Environment

Now that your trailer is clean and its systems are protected, the final step is ensuring that it stays safe and secure throughout its storage period.

Trailer Security Tips:

• Use hitch locks, wheel locks, and coupler locks to deter theft.
• Seal vents and openings with mesh or foam to prevent rodent access.
• Lock all doors and double-check window seals.

Covering your trailer adds a valuable layer of protection from UV rays, dust, and moisture. Opt for a breathable trailer cover that resists mildew. If you're storing tools, equipment, or parts, consider placing them in a trailer storage container for better organization and protection.
