Air Conditioner Replacement Unit?

Long-time lurker, infrequent poster here. I have a 1977 31' Soveriegn Center Bath that I have been working slowly to get back on the road. Looking to replace the original A/C unit on top and wondering what BTU size is needed, and what other people have installed & how your unit performs. Is there one that has an aluminum cover?

On a 31’ trailer I would go with a 15K unit. There is no noise difference between it and the 13.5K. So it’s a easy choice for you 31’ unit.
I installed the 15K Penguin II low profile unit and it works great.
Here is the blog post.

I’m not aware of any unit that has an aluminum cover. I believe Dometic offers a silver painted cover.
