I was worried about this also when I first bought the MH with the genset under the bed. The reality is the only reason that you would want to run the genset all night is that in extremely hot weather where fans are not cooling enough and you are dry camping you would want to run the AC which is much louder that the genset anyways. Even with just the fwd AC on I can't here my genset running. And again if it is that hot I run both AC's and that drowns out the noise of the genset. In 10 years and I dry camp 95% of the time I have only had to use the genset and AC's maybe twice. Fan's usually work fine. So to me this is a non issue. Just think of where and how you will camp if you are using a SP, NP, COE, or NF CG you can't run the genset at night anyways.
