Frame and welds
Look underneath with a light. Check for cracks at tongue joints, axle hangers, and crossmember welds. A frame that has been repaired is not automatically bad, but the quality of that repair matters.
Running gear
Spin each wheel to feel for bearing roughness, check for hub grease slinging on the inside of the wheels, and confirm brake magnets have wire continuity. Inspect springs for cracked leaves and worn shackles.
Deck and tires
Probe wood decks for soft spots near the fenders where water collects. Read the DOT date codes; tires older than seven years are a negotiating point and a replacement cost.
Paperwork
Verify the VIN on the frame matches the title or ownership document, check for liens, and confirm the certification label is present and legible. A missing VIN plate creates registration headaches.
Paperwork before inspection
- Match the VIN or serial number on the trailer to the title, registration receipt, bill of sale, or MCO.
- Confirm the seller's identity and authority to sell, and check for lien or ownership problems before payment.
- Photograph the manufacturer plate and record GVWR, GAWR, tire size, and VIN.
- Do not accept a manufactured trailer with missing papers as a homemade or assembled trailer without confirming the TxDMV process.
Physical inspection checklist
| System | Inspect | Walk-away signs |
|---|---|---|
| Frame and tongue | Cracks, buckling, fresh paint over repairs, rust scale, crossmembers, coupler mount | Twisted frame, cracked main rail, uncertain structural repair |
| Axles and suspension | Uneven tire wear, bent tubes, spring hangers, equalizers, bushings, bearing play | Misaligned axles, loose hangers, severe bearing noise |
| Brakes and breakaway | Controller response, wiring, magnets or hydraulics, breakaway switch and battery | Inoperative required brakes or damaged brake wiring |
| Tires and wheels | Load range, date codes, cracks, pressure, lug seats, matching sizes | Expired or damaged tires combined with wheel or hub damage |
| Deck, ramps, and gates | Rot, fasteners, hinges, pins, ramp rating, spring assist, latch security | Unsafe ramps, missing pins, major rot around load points |
Road and load test
With the seller's permission and a legal tow setup, verify lighting, brake response, tracking, bearing temperature, unusual vibration, coupler fit, and breakaway operation. Price all immediate repairs before negotiating. If identity, ownership, VIN, structural condition, or rated capacity cannot be verified, walk away.
