Now looking up we come to the range hood and vent.
Sorry wrong picture , I tried to count down , it's the next one.
Looking back to your pictures of the two campers this appears to be the final exterior vent cover . If so it might be why there was water intrusion . Most campers have an additional hood over that vent to prevent water intrusion while traveling . There is also usually a flapper somewhere to prevent cold air coming in when the vent fan is off .
If you are going to modify the hood with a fan and light you may consider replacing the hood with one that incorporates all three features , fan , light and flapper , It would still be period correct as mine has all three .
I had a major leak at the range hood vent because of poor original installation.
