Carb problems are only part of the issue. The reason you run the genny under load is to blow off the moisture on the brushes and windings. Go to you local GA airport and get a couple of gallons of 100LL. Shelf life is 2 years, but it actually will go much longer. No draining carbs, no Seafoam, no worries.
I would not suggest using 100LL gas for a built-in motorhome generator, since leaded fuel and catalytic converters do not get along well at all (and the main engine for a motorhome uses the same fuel tank). It probably would be illegal from a taxation point of view too.
I'm not sure it's a great idea for most modern small engines, too, but probably not quite as critical in terms of engine life. Avoiding putting lead into the environment unnecessarily is always a good idea, of course.
