HI all, continuing issues with my 2019 F350 Diesel 4x4. I have the trailer package as i do pull an RV infrequently. Recently, with no trailer attached, I would get warnings in the dash say "trailer disconnected" then "trailer connected" then "Left trailer light failure" then "trailer disconnected" then "Right trailer light failure" etc. Anyone else experience this? My dealer costs a fortune just to diagnosis issues. Never had so many problems with a truck. Thanks in advance Phil
