Here is 3 oil change reports from blackstone labs. I use PuP 0w20 with fram xg 10575 filter. The last oil change had 1700 plus miles on it. This oil change was the freebie from the dealer. I gave them to use my 10575 filter to put on.
Does anyone have any idea why the copper jumped up? I do not hot rod my truck!

copper.... main or rod bearing worn excessively. I'd suspect the main thrust. You can check crankshaft end play pretty easily at the front pulley.

I dunno how Bubba13 feels about it but I just got a sick feeling on his behalf.

Ditto!

Going through everything I can think of... Unless it's something internal to the lifters, I can't think of anything.

Lifters have no copper, AFAIK. GM and Ford do not, but, with FCA, ya never know.
