Avion truck campers - Hundreds of photos
Without going into too much painful detail, we had a mishap several week-ends ago. While working with sand bag crews on the Mississippi River, the truck and camper fell into the flood waters as a road...

Silver , those are some important observations about the condensation on the bare aluminum panels . I don't have a pat answer . The fact that the bare patch at the ceiling did not exhibit the condensation does not surprise me , it's the warmest place in the interior .
What I can say is the aluminum I used is thicker ( .032 ) and has a vinyl coating . I have not noticed more condensation on the new end cap .
When I did the repair I noticed that the spray foam did not completely fill the wall cavity . There was about an inch in most places which left about a half inch air space between the interior panel . When I spray foamed the back side of new exterior panel I left that same gap . As you mentioned , the foam in the end caps was originally very thin in places , less than half inch . That being said I cannot say that any of that made a difference for what you have experienced .
I would definitely not drill holes and try to spray additional foam in the cavity . I found it was difficult enough to control coverage even with everything open . Now that your end caps are all riveted together you could probably remove them as one piece by just removing outer rivets that are connected to the ribs , still a lot of work . IF that is the route you choose I would spray a very thin coat of foam on the back side of the inner panels , I think it would do more good for condensation .
One other thought on the headliner material . Some Airstream owners have reported trouble with this , not sure of the details .
Hopefully with all of us thinking we can find a solution .
