In a gasser motorhome, definitely gasoline, although a gasoline generator takes some upkeep (fog it before storage, drain carb bowl, etc.)
I know that little Onan carb is especially sensitive to spoiling fuel, but I run marine Sta-bil in my full tank for winter storage and run the genny at near full power once a month. The electric end needs exercise anyway. No problems year after year this way and only costs me maybe a gallon of gas a month.
I should run the chassis engine this way too, but I haven't. Starts right up every time I ask her to. Perhaps a 10 minute run or so would be good; enough to clear the moisture out of the exhaust and more than enough to cycle fresh gasoline through the bowl.
Don't mind me. Thinking out loud here. I digress...
