I have been going back and forth on whether to get a generator/invertor and if so how big? Lots of people say they use it only once or twice... others sound like the couldn't have made it without one...
Is the question about needing a generator for an Alaska trip?
IMO, you're unlikely to need a generator for Alaska: 18 - 20+ hours of sunlight in the summer, no need for A/C, etc.
On the way to AK...maybe you'll need A/C, but there's that many more CG's with plug-ins. If it were me and I didn't already have a generator, I wouldn't buy one for the AK trip.
