Yeah for sure! Yep, it does happen with new batteries, not the first time it's happened to me. This truck is 100% stock, no aftermarket wiring, no extra lights, etc but it did get a lot of rodent damage to the wiring harness maybe 10 years ago. Local dealership did a good job replacing but things shift around when you drive so something could've rubbed enough to allow a voltage leak.It's odd that a new battery would crap out in that short time, but it can happen. You need to run a test while the old battery is out to see if anything could be drawing it down before installing another new battery...like a small light staying on, or something thats hot leaking to gnd. This can be a real pita sometimes to find the source of a parasitic draw, but its better than slowly killing a new battery.
Really appreciate the advice and info!
