We used to own a small TT that had no air, microwave or television. Never missed any of them.
The class C has a generator, a/c and a microwave. Still no television. We generally camp in State and National parks where generator use is quite limited. The a/c is used when we are in a private campground with hooks ups. The microwave serves as another cabinet. The generator gets run once a month to keep it happy.
That said, living in earthquake country, we are happy to have the generator as a part of our "emergency kit."
Happy Camping!
