I think Frank may be correct.
The only other test requires a clamp on ammeter like a Uni-T UT210E - Amazon $50

After driving for 30 minutes and shutting the truck off, clamp the meter on either the positive or negative battery lead. It usually take 5-10 minutes for all computers to "go to sleep" so be patient. If the meter reads much more than 10-20mA you have a "parasitic load" pulling down your battery.

My 2012 Yukon XL and 2017 Suburban both had/have battery rundown protection. If anything like a map light gets left on (like one of the kids leaving a light on on Saturday) after about 10 mins the truck shuts off what ever is on. Either your rundown protection isn’t working or you seem to have some other parasitic loss (as mentioned).
I am sort of thinking if the battery was drained for some reason and it was never properly fully charged after, the battery may be shot at this point. Your battery is also almost three years old at this point. They don’t make batteries like they used to, might just be time for a new one.

This ^^^. Discharged to too low of level and won't hold adequate charge. Fairly regular occurrence (finding out about overdrawn batteries) in the first serious cold snap up here.

Drive it to an O'Reilly, Autozone, Costco or a any Battery shop and have it load tested. It's a free test.

We ended up driving a few hours today. Upon arrival at our campsite, the battery showed 12.2 and a few seconds later 12.0
Is there any way to test if there is a draw on the battery while the car is turned off?
This tells ya it's the battery. Even with a parasitic draw, the battery would be fully charged after a 3 hour drive. And if the alternator wasn't working, you wouldn't have made it to your destination.

I think that he wants to get stranded. Get a new battery and report back if it still has a problem.

Totally agree. Once they get run down once they never seem to fully recover.
My MIL's Mazda 3 had a similar problem and I was reluctant to think it was the battery because my BIL had recently replaced it. After coming up with nothing else, it was replaced with a OEM unit and the car has been fine since.

You have your warnings and data to confirm the battery is shot.
Get a new battery already.

I recently worked on an Escalade with the same symptoms. It was caused by a poor crimp connection on the negative battery cable. Where the lead terminal clamp is crimped to the copper ground cable. It would have been impossible to find it without a voltmeter.
