Long-Term Storage Tips for Trailers and Campers

Whether you’re wrapping up camping season or taking a break from life on the road, properly storing your trailer or camper is essential to keep it in great condition. Long-term storage requires more than just parking it in a lot—taking a few preparatory steps now can save you from costly repairs and maintenance later.

Here’s a guide to help you store your trailer or camper properly, ensuring that it’s ready to hit the road whenever you are.

Why Proper Storage Matters

Your camper or trailer is an investment, and like any investment, it needs protection from prolonged exposure to the elements, pests, and the natural wear and tear that comes from sitting idle. Proper storage ensures:

  • Prevention of moisture damage (mold, mildew, and rust)
  • Protection of the exterior surfaces from UV rays and weather conditions
  • Avoidance of rodent and insect infestations
  • Preservation of the internal plumbing, mechanical, and battery systems

With that in mind, here are the critical steps to prepare your trailer or camper for long-term storage.

Pre-Storage Preparation

1. Clean Everything—Inside and Out

Start with a deep cleaning of your trailer or camper.

  • Exterior: Wash the exterior to remove dirt, salt, and grime, which can cause corrosion. Pay special attention to seals and roof areas prone to leaks. Wax the surface for added UV protection.
  • Interior: Empty the refrigerator, pantry, and any storage compartments. Clean surfaces, vacuum, and remove any trash or crumbs, which could attract pests.

2. Protect Against Moisture

Moisture is one of the biggest threats to trailers and campers in storage.

  • Add moisture absorbers or dehumidifiers to help regulate humidity levels inside.
  • Check for leaks around windows, doors, and roof seams. Repair seals if needed.
  • Consider using a breathable trailer cover that repels water, but also allows air to circulate to prevent mold and mildew.

3. Prepare the Plumbing System

If your camper has a plumbing system, it’s crucial to prepare it to withstand freezing temperatures.

  • Drain all water from the system, including the water heater, holding tanks, and pipes.
  • Flush the system with RV antifreeze to prevent frozen or burst pipes during the winter months.

4. Disconnect Power

Batteries left connected can lose charge over time or even corrode the terminals.

  • Disconnect the battery and store it in a cool, dry place. Check its charge levels periodically.
  • Shut off all electrical appliances, and disconnect propane tanks to minimize the risk of fire hazards.

5. Inspect Tires

Your tires need extra care during long-term storage to avoid flat spots.

  • Inflate the tires to the recommended pressure.
  • Rotate the trailer slightly every few months to prevent the same section of the tire from bearing all the weight. Alternatively, use tire blocks or jacks to take the pressure off your tires entirely.

Choosing the Right Storage Option

Indoor Storage

Indoor or covered storage is ideal as it protects your trailer from weather and UV damage. These facilities might be more expensive but are worth considering if your area experiences harsh winters or high humidity.

Outdoor Storage

If indoor storage isn’t an option, choose a secure lot that offers some protection. Use a high-quality, weather-resistant cover to shield your camper from rain, snow, and sunlight.

Home Storage

Storing your camper at home is a budget-friendly solution, but make sure it’s legal in your area. Park your trailer on a flat surface (preferably paved) and ensure it’s shielded with a sturdy cover.

Pest Prevention Tips

Rodents and insects can wreak havoc on your camper during long-term storage. Here are some tips to keep them out:

  • Remove all food and crumbs from the interior.
  • Seal any openings where small pests could enter, such as vents or plumbing holes.
  • Place rodent repellents, traps, or mothballs inside (but use non-toxic options if you have pets).

Periodic Maintenance During Storage

Even when stored, your trailer or camper needs attention once in a while to prevent deterioration. Set reminders to:

  • Check for leaks, rust, and wear every few weeks.
  • Test and charge your batteries.
  • Start your generator occasionally to keep it in good condition.
  • Inspect tire pressure and rotate the tires periodically.

Your Trailer, Road-Trip-Ready

Taking these steps may seem time-consuming, but they’ll save you money and effort in the long run by preventing major repairs or replacements. Proper long-term storage ensures your trailer or camper stays in great shape, ready for the next adventure at a moment’s notice.
