I have been having the same problem with my 08 20ft. There are 2 places to bleed in mine. The drain taps at the back of the unit,and the drain taps under the seat where the hot water tank is. This always solves the problem until I move to another spot. Then I have to tweak one or two of the drain taps for a second or so,and the noise goes away.
