Sleeper Semi Trucks For Sale - New & Used 36-, 48-, 60-, 72- & 80-in Sleepers

Why Choose a Sleeper Semi-Truck?

Sleeper tractors marry long-haul efficiency with on-board comfort. A 72-in or 80-in sleeper lets solo or team drivers log DOT rest periods without costly hotel stops, while integrated HVAC and auxiliary power units (APUs) keep fuel burn in check during overnight idle.

Spec Decisions That Drive Profit

• Sleeper size: 36-in flat-top to 80-in high-roof—pick weight vs. comfort.
• Axle configuration: 6×4 tandems handle 80K lb interstate loads; 6×2 lift-axle saves approximate 400 lb tare.
• Transmission: automated 12-speed for fuel and driver pool; 13-/18-speed manual for heavy haul.
• Engine rating: 400-500 hp sweet spot balances gradeability and MPG; 565 hp+ for mountains or bulk freight.
• Aerodynamics & fairings: modern aero packages trim drag up to 7%, saving 900+ gal/year at 120K mi.

4 Things to Know Before You Buy

1. Total cost of ownership: budget beyond purchase price—figure fuel, DEF, insurance, and maintenance reserve of $0.12-$0.16/mi.
2. Match the truck to your lanes: spec gear ratios, wheelbase and fuel capacity to your typical terrain and load weight.
3. Inspect thoroughly: pull ECM reports for idle hours, check frame rails for rust, and review DPF/DEF service records.
4. Plan financing: weigh loan vs. TRAC lease; new models carry higher payments but lower downtime and tax benefits.

Used Sleeper Inspection Checklist

• Check bunk HVAC and inverter—common failure points after 500K mi.
• Inspect cab mounts & bushings for sag that can crack fairings.
• Scan for after-treatment fault codes (DPF pressure, SCR efficiency).
• Look for roof and corner cap leaks—water stains mean hidden mold.
