I don't agree with that at all.
As far as the gen goes, Onan recommends starting and running with a load every month. This procedure is for the generator itself, not the engine driving it. It removes any corrosion buildup on the brushes. Too much corrosion and the gen won't output AC. When that happens it shuts down and then you're screwed.

As far as the MH engine, I prefer to leave it sit. Condensation is a byproduct of combustion and it's a nasty corrosive condensation. You can let it idle until the coolant reaches operating temps but without a load on the engine it's not likely you'll heat up the internals of the engine and the oil in the crankcase enough to dry out the condensation. You'll also fill the exhaust system with condensation that typically won't dry out when just idling.

Just my opinion and I'm pretty sure I'm not alone on this one.

I live in Ontario and I pull all batteries toad,chassis, and house batteries. I keep them in the garage on the bench. That way I dont have to worry about parasitic drain, yes it does happen no matter how small. I keep them charged once a month with a battery minder, its a good one, but still I would keep eyes on myself. They are starting and deep cycle batteries and they have different charge profile. Not all chargers have a selector for agm, gel or flooded. Looking after batteries properly will save you money in the long run. Other people have different ways of doing things, hey what ever works for them great. You only have to let down once with failed or weak batteries. Then you will change the way you look after them.

BC I think what they mean is that unless your engines heat up to full running temperature for at least 30 minutes, the contaminates in the oil does not have time burn off, but actually builds more contaminates into the oil resulting in corrosion.
Also cranking a cold engine without building up oil pressure first is not good for the engine. Facts!

I've always pulled all my batteries that are not being used in the winter and hook them up to tenders, including the battery for our mower. My batteries last for 8 years or more before needing replacement so it must be helping. In fact when I replaced the original engine starting battery in our motorhome at 8 years it was because the nuts that the battery cable bolts screwed into on the battery started pulling out and I couldn't get them secured back into the battery connectors. The battery itself was still good, but I couldn't hook the cables up to it anymore.
