Fair call.
After what I've learnt with oil for the QDII diffs and transfer case, I'm confident enough that Mopar don't have anything magic happening with their oils... so I've decided to take the risk (and shorten the service interval since it's cheaper.), after obsessively checking the datasheets.
The ATF+4 spec is published, and as far as I can tell the Penrite stuff is "better" on paper.
The transfer case oil has never had a spec published, which is annoying, but the case for it just being relabelled Mobil 424 is pretty strong.
Totally understand you're thinking though. Time will tell
