The generator most coaches are built around. 6,000W Diesel 120V · 50A 30A 2-Pole 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 6,000 watts this unit will run one 13,500 BTU rooftop air conditioner plus lights, converter and small appliances. 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. As a QD-series diesel set it draws from the coach fuel tank, so there is no separate fuel to manage. Note that these ship without a battery charger.

Installation into a coach is separate and depends entirely on the chassis - whether there is an existing generator bay, how the fuel pickup is arranged, and what the exhaust routing looks like. ### Will the 6HDKAH-1044 run my RV air conditioning? At 6,000 watts it will run one 13,500 BTU rooftop air conditioner plus lights, converter and small appliances. 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. ### Why a diesel RV generator? Diesel gensets pull from the coach's existing fuel tank, so there is no second fuel to manage and no propane to run out of at a boondocking site. They are the standard on diesel pushers for exactly that reason. They also tend to last longer under heavy hours than a gasoline set. ### Is the 6HDKAH-1044 CARB compliant? 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. ## Similar diesel gensets ### [Cummins 8HDKAK-1046](https://utselectricpros.com/rv-generators/onan-8hdkak-1046) RV genset · Diesel Ships to your door Price $13,382.69 Equipment price.

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. ## Before you buy the 6HDKAH-1044 The questions that decide whether this is the right machine, answered properly rather than in a sentence on a product page. - [Why diesel rather than natural gas?](https://utselectricpros.com/guides/natural-gas-vs-propane-vs-diesel) Fuel decides runtime, refueling and what the gas side of the install costs. - [What fuel should I be running?](https://utselectricpros.com/guides/natural-gas-vs-propane-vs-diesel) Gasoline, propane and diesel each change runtime and storage. - [Would a permanent standby suit me better?](https://utselectricpros.com/generators) A portable is manual and refueled by hand.
