Many campgrounds will set a limit on how many decibels (how much noise) your generator Makes. The construction type generators (like from Harbor Freight) are made for use on construction sites, not in campgrounds. Having camped next to someone with one of those $300-500 generators, I would not like you as a neighbor. We have the Honda 2000i and Companion that will supply 13.3 amps each. One of them will run all of the 110 volt (standard) outlets and systems in our 38 foot Cameo. If I want to make coffee, use the microwave, or the air conditioner, then I have to run both. With both of them running I can stand next to the exhaust and have a conversation without raising my voice. We have owned them for over five years, use them a lot and they are still in good shape. Go for quality not low cost.
