Cummins Onan QG series
3,600-watt RV genset, lp vapor, 120V. The generator most coaches are built around.
Representative manufacturer image of the range. Enclosure finish, color and dimensions vary by model and configuration — see the specifications below for this unit.
Onan is the genset the RV industry standardized on, which has a practical consequence beyond brand preference: parts, filters and service documentation are available everywhere, and any competent RV shop in the country has worked on one. That is worth real money the first time something fails three states from home.
At 3,600 watts this unit will run one 13,500 BTU rooftop air conditioner on a soft-start, or the coach without air conditioning. Air conditioning is almost always the deciding load in a coach, and the surge at startup - not the steady draw - is what sets the requirement.
Installation into a coach depends on the chassis: whether a generator bay already exists, how the fuel pickup is arranged, and how exhaust is routed. We can quote installation locally, or ship the unit to your shop.

At 3,600 watts it will run one 13,500 BTU rooftop air conditioner on a soft-start, or the coach without air conditioning. Rooftop air conditioners draw a large surge on startup, so the practical limit is usually the starting load rather than the running load. A soft-start module on the AC changes that math considerably and is often cheaper than moving up a generator size.
LP Vapor. LP draws from the coach propane supply, which keeps the gasoline tank reserved for driving and avoids stale-fuel problems during long storage.
No. This model is not CARB compliant and cannot be sold new into California or CARB-aligned states. For Texas use that is not a restriction, but it is worth knowing if you may resell the coach across state lines.
