My first two RV's had vents for the oven that went to the outside. My current RV (which I just got) does not have an external oven vent because the oven isn't against the outside wall. I didn't make the connection until I tried to cook something in the oven and set off the fire alarm. I read the owners manual, and figured out I have to have a ceiling vent (which happens to be near the oven) open when I cook in the oven.
How many have ovens that don't have the external vent, and you have to use a ceiling vent? Any issues with this configuration?
