Okay, now that it's here, some initial impressions:
The lower A-arms look like something off a 1-ton. The rear driveshaft is about five inches in diameter, larger than that on my Ram 3500 diesel (but it is aluminum). The level plug on the Dana 60 is regular pipe thread, which makes it cheap to switch to a magnetic one.
Up front, the diff housing looks like an upside down (reverse rotation) version of the 'Cat's rear diff (good thing I bought extras of those magnetic plugs).
Filling the transfer case won't be as easy as it could be, as the exhaust runs right behind it. All four corners have what would normally be height sensors in an air spring application. Must be for the fancy shocks.
Lower links on the rear are
stout, and the geometry looks much better than that on the 2500s.

And don't drive too far with a flat rear tire...the bottom of the shock is below the level of the rim.
Also, the oil filter is up front, pointing straight forward. Haven't taken the substantial skidplate off yet for a closer inspection of that area.
Anyway, so far I'm impressed.
