TSTWe had the old TST system with the batteries that were NOT user interchangeable. Our monitors kept going out and w'e have to sent hem in for new batteries. They mostly did them for free since they haver lasted 2 years.
We finally got tired of that system, but decided to upgrade to their newer system that has user interchangeable batteries.
We like it real well.
One thing we had to have on a tire monitoring system was not only the pressure monitoring, but the temperature monitor. Some units don't monitor temperature.
We have the flow thru monitors for the coach and the regular ones for the truck.
So far, so good!
