Cummins Onan QG series
7,000-watt RV genset, dual fuel (gasoline / lp), 120/240V. The generator most coaches are built around.
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 7,000 watts this unit will run two 13,500 BTU rooftop air conditioners, or one 15,000 BTU unit with room to spare. 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 7,000 watts it will run two 13,500 BTU rooftop air conditioners, or one 15,000 BTU unit with room to spare. 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.
Dual Fuel (Gasoline / LP). Dual fuel gives you the flexibility to run from the coach gasoline tank or from an LP bottle, which matters when one of the two is scarce.
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.
