So I had this same issue with a 2013 F150 and now a 2018. When the camera works its great, but I get a black or blue screen most of the time now. doesn't seem to be a power issue. with every dealership backed up I don't want to be without a truck for weeks... so frustrating.... I can freaking back my truck up... but hooking a trailer regularly without a camera is a pain in the A**.
