Generator Advise

My wife and I are thinking about getting a 5th wheel this year and are trying to plan things out. We travel about 45 nights a year and like to go to races where we would use generator power for up to 4 days at a time. I was thinking about a Onan 5k or doing 3 Honda 2000's. We would use the generator twice a year when traveling to our vacation sites on breaks and at night. We would also use it once a year at a track. If you use your generator when traveling I would like to hear about your experiences and options.
