One of the things I hate about vehicle repair is that if they misdiagnose something, and replace a variety of parts, and it doesn't fix the problem, they have no accountability for that, even though their mistake may have cost thousands of dollars.
Did they take a sound probe and figure out where the noise is coming from? It's a pretty simple piece of equipment, and should at least narrow down the area that the sound is originating from.
Good luck,

X2 A sound probe is nothing but stethoscope with a rod on the end and it can tell if there is a bearing, or whatever, making the noise. I believe on your coach you have TWO idler pulleys that could have bearings going bad. Both of these are fairly inexpensive and should have been eliminated before they replaced any other part. One idler pulley is at the top of your belt run and the other is the moveable pulley near the bottom that is used to change the serpentine belt.
