Did you order the trailer camera? Wondering if these come with that.Nah, seems you use these with the trailering app in a process to learn the sensors one by one. Def will try out when we tow next - haven't ever had a truck where we get to configure a trailer, etc.
I have seen aftermarket TPMS and phone apps for trailer tires before. But you have to add a receiver in the tow vehicle.
