Has anyone figured this out yet? Specifically, how to use the R1T 120v outlets to charge a power bank while the power bank powers the camper?
I was disappointed to find that my new camper (just running AC and lights) would not work directly plugged to my Rivian. I installed a AC soft start...
I just noticed the same noise. I've have had the truck since November and never noticed it before. I'm 100% sure this is a new sound. Did you ever find out what it was?
