2021 THOR ARIA 4000 BUNKHOUSE DIESEL PUSHER

Asking Price: $179,999
Mileage: Approximately 38,000
Generator: Approximately 2,100 hours
Location: Near Ashland, Kentucky

This 2021 Thor Aria 4000 is a rare bunkhouse diesel-pusher floorplan offering two full bathrooms, private bunks, a king bedroom and an exceptional amount of living and storage space.

We have owned this coach for approximately three years and maintained it meticulously. We are selling because our work schedule no longer allows us enough time to enjoy the coach, so we have decided to downsize.

The Aria 4000 combines a Freightliner diesel chassis with Air Brakes, Air Ride, 360 HP Cummins engine, Allison automatic transmission and 8kW Onan Quiet Diesel generator with a highly desirable family-oriented interior.

ENGINE, GENERATOR & MAINTENANCE

The Cummins engine and Onan diesel generator have both been serviced using AMSOIL products. AMSOIL antifreeze is also used in both cooling systems.

Recent and ongoing maintenance includes:

AMSOIL engine and generator oil
AMSOIL antifreeze in both cooling systems
New fuel and air filters in both the Cummins engine and generator
New air-brake desiccant filter
Four house batteries replaced in 2025
Two chassis batteries replaced in 2025
Michelin tires DOT code 2920, excellent condition with great tread and no cracking or dry rot
Regular washing and careful preventative maintenance
