That was the point of this whole thread. There's so much confusion and misinformation out there on what specific fluid coolers exist. So for my 2011 model with a 5.8L, I traced them all to know for sure. I would tend to believe that all 11'-13' models with 5.8L and Trailer Tow Group IV package are the same (but cannot confirm this)

It seems this is accurate.
I have the package build codes for all 2011 JGC platform (should be the same through 2013):
AHX Trailer Tow Group IV..................All Vehicles.............$695 (retail)
Incl 220-amp alternator, Suspension, rear load leveling, H/D Engine Cooling, Class IV
receiver hitch & 7 & 4 pin wiring harness, Deletes rear tow hook - Incl TBB (full size spare package).
Bottom line, it says this package is available for all models. There's another common tow package (AHT) which is just the hitch, wiring, and FS spare (no HD engine cooling).
