Well. you do have to pre-heat a regular oven, and they do heat up a room. I've never had a trailer with a regular oven so I have nothing to compare my convection microwave with, but I like to do dutch oven outside occasionally as well. We don't bake much in the trailer, mostly grilling outside and cooktop for pan cooking.
