a 3000w and up inverter generator should work.
personally, i'd go with two paralled 2000w inverter generators, whether they be Honda, Yamaha or Champion.
then you'd only need to take the one 50lb. generator, if you weren't going to need any a/c. if it was just a 3000w or bigger, you'd have to lug 100lbs. or more for stuff that the 2000w could run.
though i think the new Champion 3100w inverter generator is quite attractive, but i already own a Honda 2000w.
