Hey there. We ordered our Mobile Suite with the Advantium Oven (an no lower oven). Since that time, the oven has 'died' due to too high a voltage in the RV (long story, my fault, expensive lesson!).
When investigating replacing the oven, we've decided to go with the microwave convection combo and NOT the advantium oven again.
For the type of cooking we do, we rarely used the cooking light and I found there were times that I wished that the Advantium could bake on more than just the round tray in the bottom.
The micro/convection unit is 1.7 cf and 1000 watts. It also has two shelves in addition to the rotating tray in the bottom for baking, so in theory, you can place 6 small plates in the oven at the same time.
The advantium oven is 1.4 cf and 900 watts. It only has the rotating tray in the bottom.
I hope this helps you in your decision.
Be sure to check the model that is being used by Doubeltree to ensure you get what you're expecting. Here's a link to what we've purchased to replace the advantium oven -
