The Sharp model and almost all Over the counter Microwave/Convection ovens are HOME appliances that are used in an RV. So, the cabinet will be built for any type Home Convection Oven that fits the dimensions of the cabinet. No different than having 10 year old Sharp Oven in your house and you needed to replace it. The ONLY difference between Home and RV mounts is the OEM has added a few mount screws or brackets that secure the Oven to keep from pulling loose from the wall mount in transit. If you find another Brand or same brand that fits, all you do is install the new wall mount bracket on the sidewall. Doug
