I guess that not all motorhome main engines should be idled very long for special-situation battery charging. We do this kind of battery bank charging an hour here and there, but it is a fairly modern V10 engine spinning only a medium size 130 amp alternator. I've read that it consumes about 0.7 gallons of gas per hour when used this way.
We have V10 powered work trucks in our fleet that idle for sometimes extended periods of time, usually to run PTO-driven equipment.
According to the engine computer, with nothing running, it is burning about 4 litres (a little over 1 gallon) per hour doing so.
As the load increases the auto throttle kicks in and the burn rate starts to climb.
