Also using M1 0w20AFE in the Ram 1500 4.7L. Solid oil pressure with no indication of thinning even during heavy towing a few weeks ago in 103+ degree heat.
Everything I've read seems to indicate that the AFEs are built on very solid base oils. Whether the add pack being tailored for low friction costs you anything in terms of wear protection is more of an open question, but the UOAs certainly don't indicate an issue. But we know UOAs are very limited in what they can indicate, too. I wouldn't run them in a flat-tappet muscle car engine, but anything made in the last few years that needs a PCMO... sure!
