Newbie here with a 2015 ACE 30.2. I've searched around the site and can not find anything on dampening the noise/vibration caused by the Onan Generator which is mounted at the left rear of the coach under the bedroom. It operates normally with no issues and during the day you can barely hear or feel anything but when lying on the bed there's an annoying vibration. Is there any solution that has softened the vibration or noise? Planning to install sound deadening pads under the rear floor & maybe try rubber spacers where the frame bolts to the coach if anyone has had success with this method.

Thanks

I know this doesn't help your current situation by even one shred, but you've hit on one of the reasons some are attracted to DP's. Genny in the front...

I've been thinking about buying & plugging into 2 portable Honda Generators but that's just 1 more hassle to deal with.

Our generator is in basically the same location, but we don't get the vibration you are talking about. You may want to see how it is anchored down, ours has rubber dampers on it, check to see if everything is tight.

Vibration isolators are key here.

Little rubber pucks with nuts or studs in the ends.

Have a 3 phase rotary converter that was quiet when sitting on ground but mounted to top of column for car lift and extremely loud.

Six rubber isolators problem solved.

They are inexpensive and come in many sizes and duty types.

First Look to see if unit is directly bolted to frame.

It may have internal units.

If directly bolted then check to see if it can be lifted by an inch or so.

If it can remove one mounting bolt and then confirm the weight of the unit.

Next check the fasteners for exhaust and anything else with the generator and do same removing one bolt.

You visit where the sell them and granger is good place but wholesale only so them or industrial supply.

They will look at your bolt and provide an isolator of same thread so existing bolts can be used but you will need a second set for other side.

Easy to do just a bit of work.
