Well Richard,
You are ahead of me.
Sunday in Mid-September we went to Lansing for a gathering. We took our coach. This was to provide the confidence to run to Lebanon.
She was just terrific the whole way there. No hints of difficulty - Zip Zero Nada.....
Time to come home. She fired up and ran like expected. We were about 20 miles closer to home and Mary noticed that the Digi-Panel said the system voltage was low.
We pulled off the highway and I went under the hood and checked. The engine battery was lower than it should have been at 12.4. It's the alternator (he told himself).
So, I started the APU and hit the switch to parallel the systems. I'll fix it when we get home......
Back on the highway (I-96). Mary said she had lost the power steering. We both noticed the engine temp was high and I told her to shut it down. We got "safely" on the shoulder. Coolant had spit onto the windshield. We got stopped and a lot coolant steam came out.
We called for a tow. (I will drop this part of the story here as it is a whole other cluster "operation".
When things cooled off some, then I opened the engine hatch to see that there were no belts at all on the water pump sheave.....

We got her towed home.
I inspected what I could and found the A/C sheave is packed with gummy rubber. The belt was behind (to the rear) of the sheave and jammed against the A/C line there.
When recovered, inspecting all the belts it was clear that the A/C belt has started the cascade. The forward alternator belt was damaged and is now longer than the one closer to the engine. The inner alternator belt doesn't look real bad, but I bought a new set.

Other things have drive the priority now that the coach isn't going anywhere. I have to remove the top FEAD so I can remover the cylinder head covers and pull on the head bolts. It was a wet over heat (which is better than dry), but I still have to do the check torque to see if we lost any bolt tension. I did do a plugs out crank so be sure that there was no coolant in the cylinders and that was rewarding.

So, time goes on and now we have a lot more time to get ready for spring.

Matt
Matt,

What you have experienced makes my problems seem very trivial.

What it is still annoying is the fact I went close to 24 years without any problems with belts. When I replaced the motor and transmission 11 years ago I just threw on new belts and tightened them to what felt right and never looked back.

Now I've had issues with my A/C compressor belt with my Sanden setup and the accessories drive belts. The problems I had with the A/C belt was mostly caused by me. The other belt problems are being caused by something that changed, but I don't yet know what has changed.
