Yeah, you guy are going to like this. Below is a video with the Ram director of marketing and Ram director of Engineering taking questions on the Hemi truck engine family.
At the 13:42 mark, there is a question poised to them on why Ram 6.4L requires 0W-40? They go into detail that the Ram 6.4L truck engine DOES NOT require 0W-40 and can use 5W-30 and even a non-sythetic 5W-30 at that. Also, all their durability testing was done with 5W-30.

I do not advocate deviating from the manual but gives food for thought that the call out for 0w-40 was more to align with the SRT 6.4 than any need for the RAM truck 6.4.
