Not to hijack your thread, but I had TST and didn't like them for my trailer. They would work for a little while, then loose contact with my trailer. I have a Silverado and my trailer was 21ft long. I would pull up to the trailer and every single time, one or more tires would not register. I would have to go reset that/those tires. I would be driving down the road and get a notification that I was low or hot on a tire. Get out, check with IR gun and check pressure, no problems. It sent them back. I felt I had more issues with the TST system than I had with the tires. I know others have had no issues, but my personal issues made me not want them anymore. If I were going to go do it again, I would get the monitors that go into the rim on the backside of the stem. I hear those have better antenna's and will monitor better.
