I have 3 generators just now,,, The ONAN on my rig (So quiet that when I started it at a shop one day I thought it did not start, If there is any road noise, even if it's passing cars, (the rig was in a parking lot next to a street) it completly drowns out the generator.
One Genrac 1000 portable (My "Infinite length" extension cord.. Not good for all that much but handy as blazes when I need it)
One "Contractor Grade" El-cheapo" Useful if Detroit Edison flakes on me again, and again, and again as it can run all the priority stuff in the house (Frige, Freezer, Furnance, Some lights) (Note The Genrac can run the bedroom... Including window AC!! not that I use window AC any more,,, IT can not kick start the fridge however)
My recommendation for camping... Small portables HONDA, you pay more, lots more, but you hear less, lots less A 3KW honda will not make as much nosie as my 1KW genrac and it's rather quiet The el-cheapos are NOISY
I should point out that as a UAW retiree I do not really like HONDA that much... But I can not argue with quality, and when it comes to portable generators theirs are very simply the best
