You failed to mention it has always drained a battery. Therefore given the info you shared that your efforts in putting in the e-fans killed your new battery, it would appear to be completely self-inflicted.
You also had a new battery on its first use that may not have had a full charge. Probably not the best way to use a battery by slowly trickling it down until dead on its first use.
Also the fact that no one with this platform has really seen major issues or needed a dual battery for other than camping or a fridge in the 6 or so years I have been around them tells me your situation is unique and not a typical trailblazer or electrical designer issue.
There have been some guys w parasitic drains but it was typically self-induced and with the forums help they could get it worked out by sharing all the info and not just blaming the truck or designer.
I hate to advocate weird chemicals, alcohol, violence or insanity to anyone...but
they've always worked for me.
