If the dimensions matches with your old one, I don't see why not. Some trailers or RVs would have one as a substitution from a traditional oven. Even my uncle's trailer doesn't have a traditional oven either, just a microwave with a convection oven. I have a microwave with a convection oven and it's trash, I don't think they're worth having if you already own a oven. Even my oven has a convection and I don't like using the convection feature either. I'd like to replace my Whirlpool OTR with a Sharp when the time comes cause I've always liked that brand. Maybe I might also replace my KitchenAid dishwasher with a Sharp as well since a fellow member over on vacuumland replaced his Hobart designed KitchenAid with a Sharp and has nothing but positive things to say about it.
