Asked about that when we bought our MH. Salesman showed me where you just remove a drawer and screws holding spacer above the drawer. Oven unit would slip right in. We were thinking of adding an oven for the very reason of baking rolls or cookies. However, don't need an oven anymore. A convection microwave is also an oven. We have baked cookies, rolls and even had prime rib and roasted chicken out of the convection oven. Now DW wants to throw out the gas oven in our stick house and get a convection microwave.
