Jesus?!! Over a year and you are still dealing with a truck that won't hold a charge longer than 24 hours?
That's just not right.
Just a bit of background:
I looked at a lot of trucks before buying my 2011.
I immediately noticed a lot of the trucks had been "modded" by previous owners.
Who knows what they were installing.... but they evidence was there once they removed the items before selling (loose wires, holes in the dashboard area, switches that are not factory and don't do anything when clicked).
I even test drove a nice Lariat... got back to the lot ready to buy... turned off the truck, and immediately heard a bunch of clicking that did not stop.
So.. it's entirely possible (and even likely) a previous owner has done a faulty install (or removal). This could be radio upgrades, lighting upgrades, or anything else.
My first step would be looking for any areas which could have had a previous install:
1) Radio
2) Lighting (front, rear, interior, exterior).
3) Under hood (non-factory relay packs, wires going nowhere, anything that doesn't look factory).
4) Behind rear seat (amp, subs, radio wiring).
Inspect these areas; and try to find signs of something not factory.
If you do see something concerning, please post back here and ask. Take pics.

Being keenly aware of how annoying it is trying to hunt down and fix other peoples DIY wiring BS I installed my mods using an entirely separate wiring harness and fuse/relay box. Other then it sharing a connection at the battery posts it is completely separate from the trucks factory wiring. Easy diagnostics, easy removal, and no factory wiring to repair.
Another small thing I did was use zip tie labels (can write on a little square on the zip tie); to label each wire.

Hi... Did you ever figure out the problem? I have the identical issue on the identical truck.

I never got it figured out. I brought it to a few different shops and different dealerships and nobody could figure it out. I ended up trading in the truck for something newer because I was tired of always having a dead battery.
