Bryce: I have a 2024 GMC AT4, I have trouble with the Pressure sensors on my current 5th wheel as well as the Tow Behind Trailer I had before with the Tire Pressure information that is displayed on the main display of my vehicle. When starting out I will get the proper tire pressure information but the system will lose signal after a few miles. It will come back after a while but will drop out again. It is my understanding that GMC uses 433 Mhz frequency for their TPS system. Will this signal booster work with the GMC TPS system to show trailer tire pressure??

@RonE Hey Ron, we haven't personally tested the two, but if they operate on the same frequency they should work together.
