8 Essential Maintenance Tips For Your Cargo Utility Trailer

Cargo Utility Trailer

Regular maintenance of your cargo utility trailer is crucial to ensure its longevity, safety, and performance. Proper upkeep not only prevents potential breakdowns and costly repairs but also ensures that your trailer remains safe to use on the road. While some specifications mentioned are specific to Let's Go Aero trailers, most of the information in this article serves as a helpful maintenance guide for all utility and camping trailers. By following these simple steps, you can keep your trailer in top condition, ensuring it’s always ready for any adventure. Regular maintenance protects your investment and provides peace of mind, knowing that your trailer will perform reliably whenever you need it.

  1. Check Tire Pressure - Maintaining the correct tire pressure is essential for the performance of your trailer. For both the Spec Ops and LittleGiant trailers, the tire pressure should be kept between 30-40 psi, depending on the load. Regularly checking and maintaining the proper tire pressure helps ensure load carrying capacity and stability, regardless of the climate.

  2. Check Lighting - Don't be left in the dark! Functioning lights are vital for safety on the road. The Spec Ops and LittleGiant trailers use LED lighting with a four-flat connector plug. Regularly test your trailer lights by plugging the trailer into your vehicle and checking for proper operation of stop, turn, and tail lights, as well as the yellow LED side marker lights. Pay particular attention to the condition of the four-flat plug, as fraying can cause lighting failures. When troubleshooting a wiring issue or failure, always plug the trailer into more than one vehicle to rule out lamp issues.

  3. Check Lug Nuts - Properly tightened lug nuts are crucial for safe travel. Check the lug nut tension every 500 miles, especially if the trailer is new and/or if you are using the trailer off-road. For Let's Go Aero trailers, torque the lug nuts to 50-75 ft.-lbs. This ensures the lug studs are fully seated in the hubs and prevents loosening due to the initial torque applied when the lug nuts are first tightened.

  4. Check Bearings for Proper Lubrication - Unlike leaf spring axles, all Let's Go Aero trailers feature a rubber torsion axle and a “zert” based lubrication system, which reduces the need for frequent maintenance. To maintain proper grease levels in the wheel hubs, remove the rubber dust cap and fill the hub with grease via the Zert until grease begins to swell out of the rear hub seal. This should be done once a year or every 6,000 miles. Note that trailers submerged in water require repacking of the bearings.

  5. Check Payload Is Secure and Evenly Distributed - The way you pack your trailer is important, plain and simple. Think of your trailer as a moving truck, you wouldn't load all of your hefty furniture on one side and leave the lighter items on the other; this should be your method of thinking while you load gear onto your trailer. With this being said, Let's Go Aero trailers are relatively small and are weight centered over the axle. The hazards of improper loading that can occur in larger trailers, such as fish tailing, is alleviated.
  6. Check Condition of Safety Chains - Inspect your safety chains regularly for wear and tear. If applicable, ensure that the cross chains under the tongue are in good condition when towing. This quick check helps ensure that your utility trailer and cargo remain secure during transit.

  7. Check Fasteners and Overall Condition - Let's Go Aero trailers are well engineered for lightness and efficiency, such that it's often said "you hardly know you are towing". Such user-friendly construction can make it easy to forget to check nuts and bolts periodically. While rigorous tests are not needed, it's always possible for fasteners to loosen over time, and therefore still advised to conduct a quick safety check before every trip.

  8. Check for Rust and Prevent Further Rust Issues - Rust can compromise the structural integrity of your trailer. Regularly inspect the steel portions of your trailer for any signs of rust, especially on the frame, axles, and joints. If you find rust, remove it using a wire brush or sandpaper. After removing the rust, apply a rust-inhibiting primer and then coat the area with a protective paint such as Rust-Oleum. This will help prevent further rusting and extend the lifespan of your trailer


How Often Should I Perform Maintenance on My Trailer?

Regular maintenance service should be performed on your trailer at least once a year or every 6,000 miles, whichever comes first. Additionally, always perform a quick safety check before each trip and every 500 miles to ensure everything is in proper working order.

How Do I Store My Trailer?

Proper storage of your trailer can significantly enhance its longevity. If possible, store your trailer indoors to protect it from the elements. Some trailers, like the LittleGiant and Spec Ops trailer can store vertically inside a garage with the tongue removed for compact off-season storage. If indoor storage is not an option, cover your trailer with a high-quality, weather-resistant cover. This will help prevent damage from UV rays, rain, snow, and debris.

What Maintenance Does an Enclosed Trailer Need?

Enclosed trailers require similar maintenance to open trailers, with a few additional considerations:

  • Inspect the interior for any signs of water damage or leaks.
  • Ensure that all doors, locks and gas lift shocks are functioning correctly.
  • Check the condition of the roof or lid and seal any cracks or gaps to prevent water ingress.
