Eaton Tru-Trac differential opinions?

@RustyRatRod knows a lot about rear ends. Oops, sorry, didn't mean it to sound like that.
He is a differential expert. There that's better!
Man that was just wrong. lol

I don't have any first hand experience with THESE, but OTR trucks have used a version of these for DECADES and they just don't tear up. Everybody in shops everywhere just hates them because they last forever. lol That oughtta say somethin.
