Back in the 80's we had a Dodge Omni that had two Mopar batteries last 13 months....just out of warranty. My 16 Ram has the original battery which is making me nervous, although it's working fine. Probably depends on who they contract with year to year as far as quality....

They have replaced it twice, but it is just the OEM battery. I am hearing a lot of MOPAR issues with batteries, and that a premium aftermarket battery solves most of the issues.
Had the same problem with my 2013 Longhorn .... Went to visit my son in another province and the night before I was leaving to return home my truck wouldn't even turn over ... had it towed to the nearest dealership and they put a charge on the battery (OEM) and said it was fine ... Charged me $48 and the truck was only 3 weeks old ... On my way home had a low battery warning come on ... Was able to make it home and went to my local dealership and they found the OEM battery was defective and replaced it ... Wrote to FCA and got my $48 reimbursed under warranty ... Same thing occurred with the new battery, so I went out and bought a Northstar AGM and absolutely no issues after that ... I even put my Northstar into my new 2017 RAM when I traded the 2013 in ... No issues with it during the 3 years I had that truck either ...

I would also drop some coin on a hood battery and see what happens. However, do not give them your current as a core trade in. Instead keep it.

If the new battery doesn’t solve the issue then put the old back in and take it back to the dealership. I would not take it in with an aftermarket battery.

Make sure you document this process from your description you are closing in on Lemon Law territory. But you need your service requests documented. In my state it’s 3 attempts to fix the issue, then the law kicks in.

My guess is that there is some kind of grounding issue going on with the truck that is causing massive drain of the battery. They have replaced the OEM battery with another. It’s highly unlikely you received 2 bad batteries.

I would start to beef up on your states Lemon Law.

Same here. My 16 original battery is is working fine, but I’ll most likely change out in oct or November before the cold weather hits.

Currently I am seeing about 12.9-13.2 at idle depending if it is before or after a drive. When I turn off the motor and check the battery, I am seeing almost a constant 12.7V. When I start it up the next morning, it is pretty constant at 12.3V (after sitting 12 hours). What should the normal values be? Still seems like a little bit of a draw or it could be a crappy battery, yet again. Still on the OEM battery. I plan on buying an Interstate or Odyssey this weekend.

I wonder if the IBS is not working properly. The IBS is mounted on the negative battery terminal and in part in part controls the charging system.

Probably the only thing that could draw enough current to pull the voltage down at ide would be the glow plugs and electric cab heat, you could rule those out by pulling the fuses for them.
