How to Inspect Your Trailer for Any Signs of Wear, Rust, or Damage

One of the most important steps in properly maintaining your custom enclosed trailer is inspecting it regularly for any signs of wear, rust, or damage. You should do this at least every three months or more frequently if you use your trailer often or in harsh conditions. Here are some essential steps for a thorough inspection:

  • Frame and Body Examination – Inspect for cracks, dents, scratches, or holes in the frame and body. Pay close attention to corners, edges, joints, and welds. Repair any damage promptly or consult a professional.
  • Electrical System Check – Examine the electrical system for loose wires, corroded terminals, or malfunctioning lights. Test all lights, including brake, turn signals, tail, and clearance lights. Replace burnt-out bulbs or fuses.
  • Functionality of Moving Parts – Ensure lubrication and proper operation of moving parts such as wheel bearings, hinges, coupler, jack, ramp door, vents, windows, and locks. Apply grease or oil if you hear squeaks, grinding, or sticking sounds.
  • Tire and Brake Inspection – Assess tires and brakes for wear or damage. Regularly monitor tire pressure and tread depth. Rotate tires every 6 months or 6,000 miles. Check brake components and fluid levels. Adjust brakes as needed.
  • Undercarriage Examination – Inspect the undercarriage for rust, corrosion, or damage. Address any issues promptly to prevent structural deterioration.

How to Clean Your Custom Enclosed Trailer Exterior and Interior

Cleaning your custom-enclosed trailer is about keeping it looking its best and preventing long-term damage. Dirt and debris can contribute to corrosion, ultimately compromising your trailer’s structural integrity. Here’s how to clean your trailer properly:

  • Use a pressure washer to remove dirt and debris from the exterior. Be sure to cover all surfaces, including the underside. Use a soft brush and mild soap to remove stubborn dirt and grime. Rinse thoroughly and allow the trailer to air dry.
  • Apply a protective wax to the exterior to help guard against the elements. Use a microfiber cloth or a buffer to apply the wax evenly and gently. Avoid using abrasive or harsh products that can damage the paint or sealant.
  • Vacuum the trailer’s interior to remove dust, dirt, or crumbs. Use a damp cloth or a mild cleaner to wipe down the walls, floor, ceiling, cabinets, shelves, or other surfaces. Be careful not to damage any electrical wires or connections.
  • Sanitize the interior of the trailer with a disinfectant spray or wipes. Pay attention to high-touch areas such as handles, knobs, switches, or buttons. This will help prevent the spread of germs and bacteria.
  • Deodorize the trailer’s interior with an air freshener or a natural product such as baking soda or vinegar. This will help eliminate any unpleasant odors that may have accumulated over time.

How to Lubricate and Check the Fluid Levels of Your Trailer’s Moving Parts

Lubrication is key to ensuring your custom-enclosed trailer’s components operate smoothly. Regular application of grease or oil to hinges, wheel bearings, locks, vents, and more reduces friction, extending their lifespan. Moreover, monitoring brake fluid levels guarantees safe and effective braking. Here’s how to perform these tasks:


  1. Choose Appropriate Lubricant – Select high-quality grease or oil per your trailer’s specifications, adhering to the manufacturer’s recommendations.
  • Regular Lubrication – Apply lubricant to moving parts every six months or more frequently in demanding conditions. Utilize a grease gun, brush, or spray can for thorough coverage.

Brake Fluid Check

  1. Periodic Inspection – Check brake fluid levels every three months or sooner if brake issues like squeaks or fading arise.
  • Testing Fluid Level – Employ a brake fluid tester or dipstick to gauge the reservoir’s fluid level. Add the correct brake fluid type if it’s low, ensuring not to overfill.

Brake Bleeding

  1. Yearly Bleeding – Bleed your trailer brakes annually or if you sense air in the brake lines, leading to a spongy pedal feel.
  • Effective Bleeding – Utilize a brake bleeder kit or vacuum pump to remove air bubbles from brake lines. Follow the manufacturer’s guidance for correct bleeding procedures.

How to Maintain Your Trailer’s Tires and Brakes

Proper maintenance of your custom enclosed trailer’s tires and brakes is important for ensuring optimal performance and safety on the road. Neglecting these vital components can lead to hazardous situations and costly repairs. Here are some tips for maintaining your trailer’s tires and brakes:

Tire Maintenance

  • Regular Pressure Checks – Monitor tire pressure before each trip using a gauge. Adjust pressure according to the manufacturer’s specifications on the tire’s sidewall or inside the trailer. Avoid over-inflating or underinflating to maintain handling, stability, and fuel efficiency.
  • Thorough Inspections – Examine tires for damage, including cuts, cracks, bulges, and punctures. Detect uneven tread wear like cupping or feathering that could indicate alignment or suspension issues. Replace damaged or worn tires promptly.
  • Rotation Routine – Rotate trailer tires every six months or 6,000 miles to promote even wear. Adhere to the manufacturer’s guidelines for the appropriate rotation pattern based on single or tandem axles.
  • Alignment Checks – Evaluate wheel alignment annually or sooner if misalignment signs arise. These include pulling, vibration, or uneven tire wear. Seek professional alignment services or use alignment tools for corrections that enhance handling and efficiency.

Brake Maintenance

  • Regular Component Inspections – Assess brake parts every three months, especially if issues like squeaks, grinding, pulsation, or fading arise. Inspect pads, shoes, drums, rotors, calipers, cylinders, hoses, and lines for damage or wear. Swiftly replace or repair compromised components.
  • Biannual Brake Adjustment – Adjust brakes every six months or sooner if pedal issues arise. Utilize brake adjustment tools or professional services to set the correct clearance between pads/shoes and drums/rotors. This ensures even and efficient brake performance.


Custom-enclosed trailers are an excellent investment that will last many years if properly maintained. By following these tips for inspecting, cleaning, lubricating, and keeping your custom-enclosed trailer roadworthy, you can ensure that it stays in great shape, performs well, and avoids costly repairs or replacements.
