Pointers on replacing AC / vents
Greetings, Airstreamers. Long time no post. Looking to do some work on the lifelong restoration of my 76 Overlander. Interior is stripped and looking to replace the old Dometic Quick Cool AC with a Penguin II. Also looking to replace the existing vents (I think stock with some crappy fiberglass added for ghetto sunroof?) with Maxxfans. I'm curious if anyone can provide pointers on things I'll need for this replacement.
Of note, I managed to find a Penguin II on the used market, but it was actually new in box (still had protective film) but did not include any sort of accessories. It's essentially the air conditioner (with the foam attached on the bottoms), and the air distribution box / metal plate with switches.
The other thing of note is I plan on doing white paint on the top down the line (I've read a few threads on this and haven't decided on a product but wonder if that will be necessary to do before or after, or irrelevant).
I'm guessing I need to get up there, remove the AC and vents, scrape off the bulk of the crud / old sealant, use some type of degreaser (?), strip the clear coat while I'm up there, and install.
Will I need to use any type of sealant on the new AC, or does the compression against the foam provide enough of a seal? Anything I need to buy from Dometic in advance? The interior is stripped and I plan to buy heat element / strip and tubing for condensation drainage.
Thank you for providing any info! Providing photos to show what kind of mess I'm looking at.
