Yea really. My exposure came from the dealership where I purchased my first Monaco with the 12.5 Onan. They installed a new belt using a tractor "green" belt which lasted about 8 hours use time and broke. They claimed the green tractor belts are tougher than the Onan normal Gates style belt. I call BS on that one!
Changed my second belt as PM 1500 hours or so later.
Changed the nose bearing in the generator end cap 2 times in 3500 hours although the second time the squealing I thought was the nose bearing was actually just the darn belt needing tightened
I had the old Onan with the skinny belt.
New Onan has the wider belt but I have to tighten it about every 200 hours or it will squeal. I bet if I left it squeal a while it would shred!

I would be concerned about why the belt was loose?
