Noisy Onan 4K = hack job install?
Didn't want to continue railroading the other guys thread so starting a new one. Were discussing why my Onan 4K is so noisy in my 5er and many pointed to the install and discussion around anti-vibe...

thats a totally enclosed unit
in the bottom of that picture, it looks like rubber mounts for the motor
it is possible they are too tight
you could put in a new piece of flooring, say a piece of 5/8 plywood with a hole cut for the exhaust, maybe some metal flashing/heat insulation
an set the whole genset enclosure on new mounts
look up the mounting instructions for that model
should be easy to find the PDF file, should also be in your generator manual that came with the install

from the pictures, it looks like internal springs between the power section and the enclosure floor
