2019 Ram 1500 Classic battery issue

[JErick19]

I've had my 2019 Ram 1500 classic (5.7 hemi) for about 5 months, bought it used with 41,000km. Everything was fine for the first few months until my son left my interior lights on and my battery died.
I boosted it and took the truck for a drive to charge it up and it was fine again for another couple of weeks until it died twice in one week. Went and grabbed a new battery from Costco (because of their unbeatable warranty) and all was fine for another couple of months until 2 weeks ago. Battery voltage reads 14v when running so I don't think it's the alternator.
That battery died again, tried trickle charging it but it just wouldn't hold a charge and died 2 more times in a week. Went and traded it at Costco for a new one, put it in and the truck still won't start.
Battery reads 12v but doesn't even attempt to crank, just gives a faint hum and the low battery and SERV 4WD lights come on the dash.
Anyone have a similar issue that they resolved or any advice? Thanks.

You might post in the classic area. This is the 5th Gen area and not 4th gens. That being said, you might check your grounds. Also, could be something causing a parasitic draw.
