Now that you've helped with the fridge question, I've got one about generators. I have a 27 foot class C gulfstream. I does not have a generator. I've been thinking about getting one of those quiet Honda portables. Will the 2000 Model be big enough to run the A/C when I need it? Or should I get the 3000? I'm only wanting something to use occasionally, to park in fields at the races, without a hookup. I do not mind having to turn something off to use the A/C. Your expert thoughts?
