As you are seeing there is no "right" choice. Just lots of options. I suggest you don't make a choice that can't scale for your potential increased needs down the road. That is why I went with a eu2000, have not needed AC yet at any of my non-hookup sites. If it does become an issue I'll add the companion model.
I will say that we often camp at Camp Edison on Shaver Lake, very near Sequoia and Kings Canyon, it's full hookup and we have run the AC. Although it might only be high 80s or low 90s during the day, at elevation that feels pretty warm inside the TT.
Hindsight, the only I would have done different was started with the companion model for the 30a plug.
