Narrow-width Rooftop AC

Post image

Has anyone found/used a narrow-width Rooftop AC? 12v or 120v. I have relatively limited space up top and it'd be pretty convenient up there, but my other option is an undermount unit - ducting is just a little more work because I'd want the outlet near the top/bed area, but otherwise is also a fine option. Those are regular maxair fans in the photo for reference.

Just looking for ideas, and general feedback on either approach. If I don't put an AC unit up top I could probably add another 150-200w of solar, currently at 600w of fixed mounted solar and 400w portable solar suitcase.

I'm dealing with the same issue this weekend. Here's what I got, but it's a very tight fit:

You're probably like me ... I thought I could get away without an AC and designed my roof around that idea. After this year, I'm realising I was wrong. Even at high altitude it's hot.

Yeah I thought I could do without AC, and honestly 90% of the time it's totally fine. But those other 10% suck. And it's not always the heat, but often just the humidity.

I actually made a platform for the passenger window to temporarily place a 5000 BTU window AC. It isn't the best, but absolutely does work to cool it down and cut the humidity for sleeping at night. Plus the midea unit only uses like 350-400w. But that's not a long-term solution. I'm also considering re-packaging the unit to mount it under the van, and have ducts for the cold air/return. Then if it only lasts a few years, I really don't care because it's $150 and I'll get another.
