No, it's not a generator, the generator on this one is mounted about midway back. What's a fuel cell? I was wondering about the aqua hot, but why would it keep cycling on and off every few minutes, especially in this heat. Actually I don't even think there's anyone in it this evening. The motorhome is also plugged into shore power.
I think it's the Aqua hot system. Maybe they are washing clothes, dishes or taking a shower? The Aqua systems also heat water as well as provide heat for the interior.
