Just installed a new alternator, which I bought from Amazon. There are at least 25 different listings for alternators, so I thought I would offer a comment on the one I git.

It's just a regular CS130D Series, Internally Regulated/Internal Fan 105 Amp/12 Volt, Clockwise Rotation, 6-Groove Pulley.... a basic vanilla alternator. I elected not to go with the D244 or anything exotic as even though I camp and run a fridge, I rarely come close to 'max charge' situations... no extra current draw beyond a couple of amps and I run solar (charge both house and aux)... Unless you are draining your battery bank and needing rapid replenish or drawing some serious 'I" from a cranking stereo you really don't get much benefit from a larger alternator....
The reason I am writing is that I can not believe how quiet this thing is! I have installed a LOT of alternators over the years, on many different vehicles.... I can usually hear some minor bearing noise... not with this one. I even put the stethoscope on the thing and can hear noting....
Not bad for $75 bones and no core charge....
I will update this if I have any issues with it in the future.
