just remember, nearly all campgrounds have limited generator hours.
that said, a lot depends on if you want to use the a/c and whether you have two a/c's and what size btu are they.
most likely, you'll need 3500-4000 watts of power. i highly recommend two Honda or Yamaha 2000w inverter generators paralleled.
that way if you don't need a/c, you only need to use one 50lb. one.
