Okay, OH, I'm going to continue flogging this dead horse, and...I don't even have a horse in this race!

Have you noticed if the tank internals are better protected from corrosion if continually immersed in AdBlue? I recall speculation early on that running the tank mostly empty vs. mostly full might be a contributing factor in AdBlue pump failures.

For sure, an OCD question, but...your experience is valuable.
