Hey Jeff, thanks for reaching out. That part number comes back as a Dometic penguin II, and we do carry a replacement shroud for the Penguin II. Take a look at the following:

- Replacement Shroud for Dometic Penguin II RV Air Conditioner - Polar White # DMC65RR

I'll still want you to check and make sure this matches up with your AC unit. This shroud measures 40" long x 25" wide x 7-1/4" tall so as long as these dimensions match up with your AC it'll fit, and you'll be good to go.

What happened to the old shroud? Did it catch a tree branch or some hail? Or just normal wear and tear?

Normal wear and tear! It came off in a good wind storm and shattered when it hit my yard. I’ll be buying three as the other two are fairly brittle as well. Thank you for verifying the part.

@JeffL we got a replacement shroud for our 2011 Bug County and it fit perfectly. I gave them the a/c number and they got me the exact replacement.

@JeffL We had the same thing. A tornado took the cover of the rear A/C. Luckily that was all we suffered. The part fit perfectly on our unit. It came with the needed hardware and was a breeze to put on.

@Robert Oh wow yea sounds like you dodged a bullet there with only the AC shroud being damaged. Glad to hear the new one worked out. Thanks for sharing!
