Rob, the original question was
As you pointed out by telling us it takes 7 minutes to replace the 1/10 Ah used to start the engine, to replace the 60Ah in a discharged leisure battery is going to take a long time.
True, if your battery is dead flat, then using the engine on fast idle to prevent damage to the battery by getting some charge into it is certainly a wise move - but to rely on idling a 100kW car engine for an hour is not the best way to set up for independent camping.
BTW - the 12V outputs on most generators are intended to power 12V loads. They will put some charge into a flat battery in an emergency, but are fairly lousy at properly charging a battery.
