2012 Harley edition bought 10/18

So I've been looking through the forums for about two hours and I can't seem to find a thread with my problem. 3 or 4 days ago it was really foggy and I was hauling a trailer 4 hrs away . All the trailer lights worked until I got to my destination. Loaded my load and clearance and taillights failed to come on .Brakes and turns still worked . Will be checking fuse on that .

Second problem I had tonight, I was waiting in my pickup for friends listening to Bluetooth and when they got in, the radio navigation screen went dead as well as the ac/heat controls and my mood lighting. Clock would come on in the corner of nav screen if you pushed the power or eject button. Also disabled my remote fob . I noticed no other issues besides this. Have yet to check fuse .

I'm not sure if the trailer electrical is related to the inside of cab failures.

 

Sounds like you have a bad ground some where.
