After all of my investigation, I finally took the Dodge Ram 2500 with Cummins into the dealership for a cooling system flush. The manual calls for extended life antifreeze with HOAT technology.
The dealership uses the same extended life antifreeze as cars use. We got onto their computer and entered the part number out of my owners manual; sure enough it brings up everyday extended life antifreeze. I guess the HOAT is now standard. Even the Dodge Forum and Cummins agreed.
