So what are the odds my factory batteries in my 2012 have died? The drivers side batterie is wet and the cables are corroded I have cleaned them once before, the tester at Napa showed that there was a draw while the trucks off but the trucks factory so don't know what that could even be.

Batteries die. Odd things happen when they are at that state. Every single time I have replaced my batteries, I have said WOW, it runs so much better now. I'm not sure what your codes are. Google them or someone here will answer you with information. If you replace your batteries, get the biggest and best you can afford.

One thing I always do, is I'm particular about keeping my battery terminals clean and tight at all costs. I polish them t a shine the coat them with dielectric grease.

It is very possible they have. A friend of mine has put 3 sets of batteries in his 2012 4500.
