RV A/C's tend to be noisy Even ducted ones. But here is something you might not know.
Run the fan on HIGH.. not auto but HIGH.. Yes it will be noisy for a few minutes, then your brain filters the noise.
What's more when the folks 2 sites over have a knock down drag out with lots of screaming and shouting the "White noise" from the blower blocks it from bothering you (or at least reduces it a bunch)
In my rig I sat basically under one of my A/Cs and could not even hear it to find out if it was working I had to stand up and listen very closely.
