There's camping and there's RVing...I rarely RV as in campgrounds or RV parks.A generator is a must for long stays in the hills where solar has know place parked in the shade next to a creek.
When I had my Beaver motorhome the 4k Onan was perfect for whatever, air/micro or the vacuum and keeping the battery up. Now I use 2 and 3k Honda's and I like the 3k better because it's quieter and runs the micro much easier and quieter. Can't hardly tell you turn the micro on with it but the Honda 2k screams!
If I could only have just one generator for everything, it would be the Honda 3k and I have 5 generator in all from 1200 watts to 4000 watts. My garage is full of generators and chainsaws.:B
