The Onan QG 4000 series is the long-serving workhorse of RV gasoline and LP power — a constant-speed, single-cylinder OHV set built to run one rooftop air conditioner plus the rest of the coach. It is compact and light enough for travel trailers and Class C motorhomes, and quiet enough to meet National Park Service requirements at 68 dB(A).
