A used tow truck can be a bargain or a $15,000 mistake. The difference is a disciplined pre-purchase inspection.
Chassis & Drivetrain
- Frame rust — especially crossmembers behind the cab
- Rear axle seal condition (leaks under the differential)
- Transmission cooler routing and leaks
- Cummins / PowerStroke / Duramax service records for DPF/DEF work
- Cooling fan clutch engagement
Body & Deck
- Deck cross-member rust and weld quality
- Winch line free of frays, kinks, or 'birdcaging'
- Hydraulic hoses for cracking near fittings
- PTO engagement smooth, no gear grind
- Wheel-lift extension full travel without binding
- Toolbox latches and light bar function
Paperwork
- Commercial title (not salvage or rebuilt)
- Weight on title matches truck (needed for USDOT)
- Federal ID plate and VIN present and readable
- Prior USDOT number, if any — check FMCSA safety score

Spend $250–$500 on a mobile diesel mechanic pre-purchase inspection. It's the cheapest insurance in the business.
Frequently Asked Questions
How old is too old?
For motor club work, 10 years max. For PPI/cash-only work, mechanicals matter more than age.
Should I buy from an auction?
Only if you can inspect on-site. Sight-unseen auction trucks are almost never a deal.
What's the top hidden cost?
DPF/DEF emissions repair. A single delete-reversal repair can hit $5,000–$8,000.
