I have a very similar sound in my 2001 P32 Fleetwood Flair that almost duplicates your issue.
I have had the noise since the coach was new. Now have 50,000 miles and nothing has changed.
Serviced yearly regardless of mileage. Oil, grease, etc. Tranny also serviced.
I have checked everything that has been mentioned so far with the exception of removing the driveline to check u joints and have found zero issues.
Even replaced the fluid in the rear end. Fluid was clean with no signs of abnormal wear or particles, etc.
I have come to the conclusion that it is simple harmonics caused by extended driveline and possibly poor design. But can’t confirm that.
I do know that with the RV unloaded, the sound is not present. That’s my reason for design considerations.
I will be following this thread so keep us informed as to what you come up with.
