RV generators
Onan is the genset the RV industry standardized on, which matters for a practical reason beyond brand preference: parts, filters and service documentation are available everywhere, and any competent RV shop in the country has worked on one. All 12 models, quoted directly rather than listed — ask and we will price any of them.
QG series — gasoline, LP and dual fuel
2,500 to 7,000 watts. The standard fit for towables and gas coaches, drawing from the coach’s existing gasoline tank or propane supply.

QD series — diesel

Models marked “No” for CARB cannot be sold new into California or states following California emissions rules. For Texas use this is not a restriction.
What it is for
Power on the coach, away from shore power
Boondocking, a campsite with no hookup, or a rally where the power pedestal is already full. Without onboard generation the air conditioning, the microwave and the converter all stop when you leave the plug behind.
Why it becomes urgent
Summer travel in Texas means the coach air conditioner is the load that decides whether the trip is comfortable.
Who buys it
Motorhome and coach owners running Onan QG and QD gensets.
