My DW uses ours pretty often; and has over the years in several different rv’s. Her experience, as just told to me is, really no different than home. Wouldn’t hurt to have a thermometer (though get a small one....racks are pretty close together). Also, a pizza stone, air bake pan, or something similar can’t hurt.
Someone commented that most don’t use the oven....wouldn’t have an RV without one! Now the dishwasher... that’s a waste of good cabinet space, :B but you can store stuff in it. For example....that cast iron fry pan for corn bread! ;)
