OK....you've got one of the nicest interiors I've seen....here's the deal...
Original window and vent seal were done with linseed oil putty strips...they dry out and crack...that's why you'll see staining around the windows and vents....Pull the windows off...clean off the linseed oil putty...use a heat gun, it'll soften the putty......and replace it with butyl glazing tape....a 1/2x1/8" tape will do (available at any glass shop)....do the same for all the eyebrows....you'll have the thing sealed up for the winter...protect that ash interior....it's a jewel
you can use glazing beads as an alternate...I would install 2 lines of beading and remove the excess that smooges out.
Congrats....I wish my interior looked like that
After looking at your vent and the front...you'll want to do those forward and rear gutter seals too....they tend to pull away from the camper. be careful with the aluminum guttering....they don't make it anymore and Alaskan doesn't use it anymore...consider replacing the vent....Hail damage....looks like a shotgun....
