I run the Honda 2000 and the companion. I love them. Yes they are pricey but high quality, quiet, and lite, I use them every where. I also support the company that supports my family (Honda employee just a different division)
With that said my brother-in-law has the new Predator Series 2000 Watts, and he bought the conversion kit. They are compatible to the Hondas in every way I listed above except price, if you catch a sale they're half price. Consumer Reports rated the Predator brand as the Best Buy for the buck.
What ever brand you decide on... my personal opinion would be the two smaller lightweight that you can parallel. They are light enough that you can use them anywhere camping or not, and your spouse can easily move them around. If there is a catastrophic failure on one generator, you still have one left to get you through the remainder of your trip.
