Tire Linc came with my RV and has worked fine so far. The pressures shown in app are in sync with pressure found when checking manually. I just prefer to use the GM Trailer TPMS if I can get up and running, I'll know after tomorrow when I get those sensor installed in tires.
Make sure your back trailer tires are less than 23 feet from back bumper. I hade to move my module from behind the license plate to below of the bumpers. Longer trailers and fifth-wheels are a problem.
I ordered the NAPA valve stems and my GM trailer tire sensors should be here today. I am hoping the sensor will if NAPA valve. I’ve already moved the receiver out from behind the license plate for better reception.
