Battery Drained overnight. What should I check next?

2018 4x
Battery is 1 year new, heavy duty.
Drained dead completely, after a couple of days while not used. No dash lights, nothing.
Previous drive was just a couple of miles, so I think it's a current drain issue and not a charging issue.

There are no aftermarket electronics, sound, etc.
Battery terminals and wires are clean and tight.
Wasn't banging around on trails so nothing should be knocked loose/shorted.

Once the battery is re-charged, I'll test the alternator for 14V, check visually for any loose wires, not an expert at spotting them as I spend more time in the driver's seat .
And then I guess a parasitic draw test
(using voltmeter, pull fuses 1x1 to check which circuit is draining) >
How to Find a Parasitic Battery Drain: 11 Steps (with Pictures)

Is there anything I should check first, maybe a relay, or anything else that is known for shorting out? Need to get back on the road.

Thanks!
