I FINALLY did. Kept getting delayed due to winter storms. Service dude said sometimes there’s an issue with the truck switching between AC and DC - but they at least knew of it and knew the fix. Adding a picture of what they told me.
Yes, got it during Christmas. Only thjing I had plugged in was some lights in the bed. My appt for it (and a handful of other things) is this coming week and can give an update when I hear from the Service Center.
