Very interesting about that 0.8GPH number..... I have wondered what that burn rate would be. Wonder if that's a good number???
There are a couple problems/issues with running the engine at idle rather than running the generator.

First, at idle the engine does not adequately burn the fuel thereby causing the build up of carbon and other deposits in the valve train and leading to higher valve train related failure rates.

Second, at idle the engine may not reach the operating temperature over time to adequately had vapors generated in the oil pan and lubricating system. This may result in reduced oil life and increased emission control problems with crankcase ventilation components and oxygen sensors.

The Ford manual states that with excessive idling the engine oil and filter must be replaced every 5000 miles rather than the at 7500 mile intervals under normal operating conditions. Also, according to the service schedule the spark plugs, under excessive idling, must be replaced every 60,000 miles rather than every 97,500 miles.

The Ford engine is meant to power the vehicle down the road, not cool the coach when you are sitting in a campground. The generator on the other hand is meant to provide AC power to the coach when shore power is not available.

Although it is not important to me (I rarely boondock), one might look into what makes a "Quiet Generator" quiet and see if those principles can be applied to the Onan line.
