We are solar and use a H 2000 for backup. I have only had to break the genny once this year. When I do use it its only for the task at hand. I guess if your in the south or a highly populated area you have no problem with the sound of a construction type generator heating water all day.
I think it would be reasonable to set some decibel limits in any campground that can be reserved on line ththrough campusa or reservamerica. I'm not against the use of generators but the loud ones are horrible.
The last trip we took the guy across from me had earplugs in while he was unloading his truck and near his generator. He even paid for the spot next to him so he could run a 100' cord to his rv because the genny was so big he could not move it by hand.
