I like my convection/microwave and also like the builtin generator. Have you thought about a oven delete and convection/microwave add?
I like being able to start my generator easily, but I also don't run it for long periods of time. I don't go camping in the hottest weather, and if I'm just going to sit in a the camper because it is too hot outside, I might as well stay home. In that respect, running an AC for extended periods of time isn't needed by me.
Most of us have reasons why our setup is best for us, the hard part is figuring out what is "best" for how you plan to use the TC.
