Noisy RV Rooftop A/C unit

Yes they are noisy but then again it is right there...not outside in backyard on a pad.

Really noisy.....remove ceiling grill and check function of blower fan wheel (turn fan on with grill removed and watch for excessive movement/wobble) also check duct work leaving discharge plenum (loose materiel, loose ducts etc.)

And make sure registers are open & flowing air.....restriction will cause noisy fan

Ours is kind of like that. If we need it on at night, we run the one in the front so it is less noisy in the bedroom.
