Cummins Onan 6 kW Diesel RV Generator — 6HDKAH-1044

The Onan Quiet Diesel series draws from the coach's own diesel tank, so there is no second fuel to carry and no LP bottle to run dry — the reason it is the standard generator on diesel-pusher Class A motorhomes. A liquid-cooled engine under a sound-insulating housing runs at constant speed on a vibration-isolated mount, and the set is sized to carry multiple rooftop air conditioners at once.

Features and benefits

• Runs off the coach's diesel supply. One fuel for the chassis and the generator.
• Liquid-cooled diesel. Built for long run hours and high ambient temperatures, not occasional use.
• Sound-insulating housing and isolated mounting. Computer-controlled constant-speed operation keeps the note steady rather than surging with load.
• Pure sine wave output. Safe for sensitive electronics throughout the coach.
• Self-diagnostics. Fault codes reported at the control rather than diagnosed by guesswork.
• Serviceable. Designed for access to filters and routine maintenance items in an RV bay.
