Generator Vibration/noise, Isolator

[Jay_Pat]

I have two Honda generators mounted in a alum tool box on a steel frame, all mounted on the back of my trailer.
When I run the generators, there are vibrations and the sound resonates loudly in the trailer. The living room is at the rear of the trailer. Not pleasant to use.
I have a heavy cloth type material (about 1/8" thick) between the steel frame and the tool box. It is the same material that goes between alum fuel tanks and the strap that holds the tank to the saddle on a 18 wheeler.
I am thinking about checking in with the local Onan repair shop to see what they suggest.
Thanks for any ideas and help!!

I think you just found out why so few folks with portable generators run them attached to the trailer. Low frequency vibrations into the frame are like a voice coil in a speaker. and the trailer inside shell is like the speaker cone.

If you find a solution, post it, I and others would like to find a solution. I just make sure mine is on the ground and not on the trailer when I run it.
