First, its all relative. And generally speaking, roof R/V air conditioners are relatively noisy. At least they are inside the camper. Its a fact of life. The fan is loud. Noticeable or even substantial vibration when the compressor (not condenser) kicks on is normal. Therefore you should compare it to other campers to see if you have an unusual case, or if it is a defective unit or installation.
The aforementioned Micro-Air easy start
is a common way to quiet the "thump" and vibration when the compressor comes on, and also to use the A/C with a generator
that otherwise would not be powerful enough. However it does not quiet the fan.
And some other models of roof A/Cs are less noisy, but others will have to help with that because I dont have the experience to share in that area.
If you determine that it it running normally then maybe you can get used to it. My Dometic Brisk Air A/C is very loud, and I hate it when I am awake. But I sleep with it just fine.
