Why Owner-Operators Look for Fleet-Maintained Trucks
Fleet trucks often receive better preventive care than privately owned units because:
| Fleet Practice | Benefit to Buyer |
|---|---|
| Scheduled oil analysis | Early engine issue detection |
| DOT inspections | Safer braking and suspension |
| In-house mechanics | Consistent service quality |
| Standard parts | Easier replacements later |
This reduces the chance of hidden neglect.
What Types of Trucks Are Typically Sold

Most listings include:
- Sleeper cabs (high-roof)
- Day cabs
- Automatic transmissions
- Fleet-standard white paint
- Aerodynamic fairings for fuel efficiency
Common specs include Cummins or Detroit engines paired with automated manuals.
Typical Mileage and What It Means
Fleet tractors are often sold between 350,000 and 550,000 miles.
For modern diesel engines, this is considered mid-life, not end-of-life—if maintenance was consistent.
