This thread is helpful because I just unlocked my van to show friends in town and had the same thing happen. Not having driven it in a few weeks the battery was dead. Definitely going to install a switched trickle charger off my shore power, but for a 2018 with 21K miles, is this about the time I should replace OEM battery anyway?

I've already got one car with a parasitic I've been chasing for three years, I'm hoping this isn't another - that and the oil (cooler?) leak... I left Ford hoping Ram would be at least a little more reliable!
