Ford has an "individual trailer TPMS" option that will display the trailer sensors in the same screen as the TV sensors. Warning is for pressure only, temperature is not monitored. The trailer sensors are wireless internal sensors, and the option includes the wired controller that is required to be installed on the trailer, and which connects to the TV wiring harness. This controller is user installed. The MSRP for the option for 2021 is $500 on a Ford super duty truck. I ordered a 2021 F-250 a couple of weeks ago with this option.
Ford also has an option that contains both the trailer TPMS and a wired rear view camera for the trailer. The camera displays on the TV screen only when the TV is in reverse. I opted to stick with my separate rear view camera display so that I can have an always-on trailer rear view display.
