Serious rust or perforation is a walk-away.

If equipped, check for leaks and correct operation.
Suspension
Lower ball joints, upper ball joints, and bushings at 150k+.
Drivetrain
Verify transfer-case and diff fluid service on 4WD examples.
Modifications
Lifted trucks often hide accelerated CV, ball-joint, and driveline wear.

  • Fuel economy is a genuine trade-off — 17–19 mpg real-world is typical.
