Another project I’ve been sitting on for a long while is to replac3 my brittle and deteriorating AC shroud. I’ve had the part for well over a year but, well, you know . . . Clear weatherproof tape always seemed to be the easy way out. However, every time I went on the roof my toe would graze the shroud’s side in passing, inevitably knocking off another piece of the thing. See photo.

I bought the replacement online through Amazon, but for the life of me can’t remember the vendor. It may well have been Dometic itself as it is a Dometic product rather than some aftermarket unit. You’ll need to identify the model number of your unit as the model “name” Penguin can apply to quite different units. The instruction sheet that came with the shroud had instructions for “earlier” and “later” versions, without identifying either by year(s). See photo. The unit comes with various lengths of self-adhesion foam tape that gets attached in a specific manner on top of the unit so that the shroud can sort of perch on top of the foam. You’ll have to peel/scrape off the existing foam first. See photos. Some of the old foam was so disintegrated that it turned to dust when I touched it. That’ll have to be vacuumed or mopped up.

The shroud is fastened to the frame by four screws which I found responded to a Phillip’s head screwdriver, although I’m not entirely sure they actually were PHs. The holes on my replacement shroud were perfectly aligned with the screw holes in the frame. I didn’t end up stripping all of the old foam as much of it was in good shape, but I’ll save the unused portion for later if it becomes necessary.

The replacement went on quickly. I disposed of the old one by putting it on the driveway and lightly tapping it with my foot. It collapsed instantly in many small pieces. Long overdue.
