One of the reasons I purchased my 2019 RAM 3500 was for the ability to monitor trailer tire pressures. When I talked to my dealer about purchasing the sensors for our trailers they had no clue what I was talking about. After talking to another couple of dealers here in town I got the same answers. They had no clue what I was talking about. Even after I showed them the videos and the setup on my dash they were unable to help me. Has anyone experienced this problem and if not. Does anyone know what the part numbers for the sensors for use with the Trailer TPMS system on my 2019 RAM 3500 are?
