Just in time for fall, hubs got the air conditioner installed! That may seem like sarcasm, but I really am happy the AC is in. We got the Coleman Mach 8 low profile air conditioner with a black shroud. There was a breeze of negativity blowing from the general direction of the Airforums about the quality and quantity of noise this particular AC produced. However, when I turned it on, I wasn't struck by it's noisiness. I stood inside and outside the trailer to give a good listen. Granted, I haven't done a side-by-side comparison of AC loudness with other models, but I found the noise level to be very reasonable, especially considering the service it provides.
When compared to the exact same model with the exception of the low profile, I am so glad we spent the extra money to get a shorter one.
The trailer in the neighboring bay:
The inside shroud is unobtrusive and we got the heat strip so it blows moderately warm air with the dial turned all the way to hot.
