I hauled a 1,000 watt generator around for a couple of years and almost never ran it because I don't use a lot of battery power. Hauled a Honda 2000i around for a few more years and seldom used it since it would not reliably run my air conditioner. I now have a 3500/4000 Champion that is often used when taking a lunch/nap break in a rest area, or for a few hours in a truck stop or Walmart when overnighting in parking lots. My point is, try to figure out how you will actually use one before spending your money. 30 amp service was what I wanted and got. I can boondock silently for a few nights with batteries and a little solar.
