Jayco greyhawk generator ?

I have a greyhawk 31ss with a onan microquiet 4000. The minor issue im having is that when running, or even if there is alot of movement of the coach when parked (and im sure when moving) there is an annoying squeak i believe it is more than likely the mounts, but i cant seem to locate the exact cause. Also, the exhaust comes from the rear of the gen and goes forward and exits just behind the drivers side running board, and i noticed that the pipe is starting to sag where it makes the 90 degree turn to exit toward the running board. Can someone tell me if they also have the squeak and how they fixed it, and how many mounts are on theirs for the exhaust?
Thanks!
