I know some disagree with me, but I still think a simple, inexpensive pneumatic belt tensioner pushing on the back side of the PS/alt belt at its longest run would go a long way to increasing belt wrap at the alternator thereby decreasing or eliminating belt squeak there and at the power steering pulley. It would mount on a simple pivot point and push against a stationary member. If I still had a GMC I think I could prototype one in an afternoon.

Thanks Delbert :d

Jerry, Did you guys have issues with belt squeal on your coaches?
I had a very persistent belt failure issue but it turned out that I just wasn't re-tensioning after they stretched.
After readjusting all the new belts after install and a few miles we've have 3-5K miles without a hiccup (knock on wood).

I think that the percentage of increased wrap would be negligible, but taking all slack out instantly on the slack side during high demand should
work. I had posted to Matt that on an old 8HP Ariens they succeded with a single V belt with the tensioner (lever and spring loaded) on the slack
side. I found that the belts only failed due to dry rot not overpowering.

Why a pneumatic tensioner? Whassa matter with a simple spring or fixed tensioner? On verious vehicles I've had both without problems.
