Noisy A/C

[S.Fleckio]

Its been nice having a place to cool off when its 95 degrees at the campground. Only problem is the rooftop Dometic AC on my 174BH sounds like a jackhammer whenever the compressor kicks on. I'm gathering this a common issue, does anyone have any ideas on how to quiet it down a notch?

You should look up your unit and see if there are any rubber feet or vibration isolation and make sure they are ok. Then check and make sure your bolts that hold it onto the roof watertight gasket are to loose or tight.

After that I would suggest looking at something like the WackOProducts silencer systems.
Or earplugs.
