I have a 2021 f250 King Ranch that I am going to use to pull a 5th wheel. Initially when I got the truck, it was not set up for a 5th wheel. I have had the puck system put in, but am having extreme difficulty getting the correct plug for in the bed of the Truck. I have the pro backup assist sensor for the 5 th wheel and the camera for the back of the trailer. Ford dealer cannot find the plug anywhere and they also think that with the camera and sensor plugged in they will conflict since they won't be in the same plug. Has anyone retrofitted their truck and had this issue?
