Sleeper Truck Truck FAQ
What is the difference between a raised-roof and flat-top sleeper?
A raised-roof sleeper (also called high-roof) has a standing-height compartment of 6+ feet, giving drivers room to walk around, cook, and sleep comfortably. A flat-top sleeper is lower and more aerodynamic, typically used on day-cab replacement sleepers where drivers stop at truck stops nightly rather than living in the cab.
What should I check when buying a used sleeper truck?
Pull the ELD or ECM data for actual idle hours vs. driving hours — high idle hours burn engine life. Check DEF system, DPF, and EGR valve condition (expensive repairs). Inspect the APU or shore-power system. Review the full maintenance history and run a VIN check for accidents or title issues.
How many miles is too many for a used sleeper truck?
Modern Class 8 engines (Cummins X15, Detroit DD15, PACCAR MX-13) are built to 1,000,000+ miles if properly maintained. 400,000–600,000 miles on a well-documented truck from a reputable fleet is often a better buy than a low-mile truck with unknown history. Look at engine hours, not just miles.
