Try this:
Mach 8 hush kits I did it to my Navion 24J
and it made a huge difference (super quiet on the outside). On low it is very bearable inside.
I also took the ac cover off the ceiling to check things out, and found some springs under the 4 main mounting screws. I had a hard time finding out what the purpose was. The springs are there to achieve the correct amount of tightness to the roof seal (between the ac base and roof).
What I found was that my springs were squashed and mangled, and the frame they went through was bent. I spent some time straightening the springs and the frame and reassembled. The springs are intended to be tightened until the spring spaces are just closed,
I turned ac on and a lot of rumble (droning( was gone.
