We have the Breville as well, the large one. It has a 14 x 14 tray. I can’t say enough good things about this oven.
Very accurate, heats up quickly, cooks very evenly. Better than either of our ranges.
Cook full size casseroles, pies, roasts.
Not cheap but worth it. And the best toaster ever.
In a dream world my RV world not have the gas oven and have this built in.
