The pantry in the 28' FB International is deeper and a normal microwave is mounted sideways in the pullout pantry IIRC.
We elected the option of a stovetop with the convection microwave underneath. You can preheat it and bake things just as in a normal oven. We use either soft silicone cookwear or pyrex. It's got to be square or small enough to go around on the turntable, so we probably will never attempt cookies. But susie needs it to nuke hotpacks for sore whatevers. Overall we're glad we made this choice -- but Airstream must not have done many of these when they did ours.
