Our 2012 Flying Cloud is a 27FB and the microwave is in a pull-out cabinet to the left of the stove. We've got a top cabinet, the micro wave, and a lower drawer.
We like both the micro and stove - but if we were going to love with just one, we'd get rid of the micro.
To each his own.
What size/configuration trailer do you have? Is the storage space I described above similar to yours? If so, you could probably add it.
You could also just get a table top microwave if you wanted to stick it in a closet and bring it out when needed.
