I've only been doing this a few years with a camper but I'd keep the microwave and Delete the onboard genny.
If you do that, realize the AC might not work with a 2k Honda. If ordering, I'd make sure I got an AC that would work off of 2000w or less.
My only gripe the few times I have been around on board genny rigs is the noise. Inside the camper is loud with the generator on.
All of this depends on where and how you use the camper too. I'm typically in the boonies with no campground so I can set the Honda off in the woods and barely hear it in the camper.
We use the micro wave and oven all the time.
I've met people who say "I never use the bathroom, oven, micro, etc in my camper."
Thought that's why you got a camper. If I didn't use the amenities, a good tent and a cot and camp stove are much cheaper and easier to pack than a camper.
