On board generator exhaust?

For fifth wheels that have a generator built into the front storage area (more or less under the bedroom) how are they exhausted? I'd be scared to sleep with it running. How noisy are they?

    The Onan's at least the one I have runs very quiet, In fact they are advertised as the quietest Plus they run at a constant speed so although the QUALITy of the sound (Volume, and waveform) may change with load. the actual note does not.

    Your brain very quickly tunes it out.
  • I purchased several Carbon Monoxide alarms then installed Lithium batteries. Now they are in the gen shed still active.

    Have a CO alarm in your bedroom and test it regularly and replace the battery yearly. You want the alarm to be mounted at sleeping-body level.

    When the power goes out and I know it's temporary, I'll fire up the Harbor Fright 800 watt on the roofed patio but then retreat indoors where there is a CO alarm
  • When I installed my generator, I ran the exhaust to the rear of the coach and use a Gen-Turi to get it above the roof line.
  • They are very quiet when running. Noise is not an issues.
    While sleeping exhaust is an issue. I strongly suggest using Genturi if there are others parked close to you or if you plan to use while sleeping.
  • FWIW, I have a 96 Southwind. The Onan 5500 is under the bedroom. It's very quiet when running.
  • I have the Onan 5500 under my bedroom and I can't hear it all when the a/c is on. The exhaust is out the bottom of the gen mount area and exits to the left front side of the RV. I do have a Gen-Turi system that I put on when using the generator in cramped areas.
